Those of you who watch this channel know how much I hate almost every tool belt out there. So Diamondback Toolbelts reached out awhile back and offered me a sample if I agreed to do a review. Well...you know I'm honest in my reviews, so here goes:

I think all in all the idea of this bag is a good one if you're a general construction worker. I don't recommend this for electricians, or anyone with SPECIFIC tool needs as it will surely disappoint. There are a lot of little quirks on the belt that seem like a "cool idea" in theory, but I find that 50% of the belt misses the mark on the essential functions of the thing - making any "cool ideas" added lose all purpose.
The hammer holster is really cool, and seems to be the true selling point of this rig. The pockets where tools slide in and out of don't allow for electrical hand tools to fit in snug, and I can quickly tell that electricians were not thought of in the design of this belt. This is not abnormal, honestly, all electrician belts/bags are sub-par in my opinion. Can't wait to find the perfect tool bag some day!
Anyways, thank you Diamondback for sending me a free bag. I really do appreciate the thoughtfulness however I ended up giving this bag away to a handyman I know. I need something more specific.

Surge Protection. Why, where, and wut?
NEC 2020 code requirement changes
The National Electric Code (NEC) sets the standard for electricians and electrical work across the US, with the arrival of it’s 2020 edition adding some substantial changes to the codes on surge protection. The most notable of these changes can be found in “Services” article 230.67, which states that any new or replaced service supplying a dwelling unit must be provided with a Type 1 or Type 2 Surge Protection Device. Residential Services will no longer pass inspection in most jurisdictions without a surge protection device either inside the service panel or immediately adjacent to... Which is kind of a big deal. In addition, NEC has moved the entire article of Surge Protection Devices from 285 in the 2017 edition over to 242, renaming the article Overvoltage Protection in order to incorporate surge arrestors over 1000 volts. Lastly adding a helpful table (Table 242.3) listing other sections of the NEC that mention surge protections for specific uses, such as fire pumps and data centers.
What is a surge?
A power surge or “transient over-voltage" is a spike in voltage to an electrical system that can reach thousands of volts so instantaneously that it has to be measured in fractions of a second. There are multiple types of surges, the most common is caused by large loads with-in the electrical system (e.g., Air Conditioning units, elevators and motors). These surges created by appliances and motor loads are typically oscillatory, or one event that remains just long enough to cause a “rippling effect” in the system and will shorten the life of sensitive electronics. The larger less frequent surges are caused by changes to the grid by the power company and lightning strikes to the grid itself. These surges are typically much larger impulse transients, meaning one spike that dissipates immediately, and can be detrimental to a building's electrical system...

Often it's difficult to understand what certain wires are called when you begin your path in the electrical trade. Here are some terms and what they mean.

As an apprentice, I remember always shaking my head trying to understand what the difference between a service-entrance conductor and a feeder was. It didn't make sense to me that some branch circuits look like feeders, and on top of it all, why do some of them get called homeruns?
Well a homerun is a specific term that means "comes from a breaker." A lot of receptacles and light switches have jumpers between them, but only the wire/cable that goes from the first device in the circuit, back to the electrical panel, is called the homerun. This is to help identify it as the conductor that is bringing the incoming power - which is very useful for both wiring and troubleshooting the circuit.
A service-entrance conductor is a wire that comes into the service. It connects the utility power to the meter and main disconnect out at the service. In that service panel you'll most likely have breakers, which will have either feeders or branch circuits leaving from them. Feeder describes a wire or cable assembly that leaves a breaker and goes to another breaker. We call the wire running between two panels a feeder for this reason. This is not always the case, sometimes there are feeders run from a breaker to a disconnect, then down to a piece of equipment, then back up to another breaker in a new panel. These are all still considered feeders.
A branch circuit though, is any circuit that branches off to multiple devices. Then a multi-wire branch circuit is simply when multiple circuits are run together in the same raceway or cable assembly - often sharing a neutral (grounded) and ground (grounding) conductor.

Electric Vehicles are becoming more and more popular on a daily basis. Maybe you own one yourself or know someone that does. Either way, one of those vehicles are going to need a way to charge their batteries. In this latest episode of Electrician U, Dustin walks us through the process of installing an electric vehicle charging receptacle in a residence.

For most EV chargers a Nema 14-50R receptacle will be used. Most of us have probably seen one of these receptacles before in our homes. They are the same ones used for the oven! These receptacles are rated for 50 amps at 250 volts.
The very first step in the process would be to hire a professional electrician to install the receptacle. Now this would not only be for the non-electrician, but also for an electrician lacking the experience of installing this type of circuit. The second step in the process would be to remove power from the panel you will be installing the wiring to, so we aren’t working in a hot panel. Once we have that done, we need to figure our WHERE the new receptacle will be placed so the two-gang box can be installed. If you are installing the receptacle in an existing house, you will most likely be installing an old work box (sometimes called a pop in box). A tip here is to use a PENCIL (not a marker) to draw the outline of where you want to put the box. That way if there is a stud or other obstruction, you can shift the location to adjust and not have an unsightly pen mark left over!! To finish this portion of the installation, simply cut out the substrate to expose the void in the studs the size of the box you just marked, and you are ready to install the wiring!
For this installation, Dustin is using 8/3 NMC. So, it has 3 #8 conductors (2 hots and 1 neutral) along with a #10 bare copper ground. The cable will need to be fished down the wall to the box location. This will result in you having to go DOWN to the location where you cut the hole in the wall and reach inside the wall cavity to grab hold of the cable and pull it out of the hole. Once the cable is out, simply knock out one of the tabs in the box and pull the cable thru it and secure the box to the wall. Make sure you do not Over tighten the screws on the wings so those little tabs don’t break off.
Once the box is installed and wire is in place, then carefully remove the outer insulation from the NMC with a sharp razor knife. Don’t put pressure on the cable with the knife, just let the blade score the insulation gently so it can be removed. Next, remove just enough insulation for each conductor to go into the port on the receptacle. Put those stripped conductors into their respective ports on the receptacle itself and then tighten them down (making sure you are not over or under tightening them). Carefully fold the conductors back into the box and secure the receptacle to the box making sure that the bare copper ground wire is NOT contacting any other exposed metal parts of the receptacle or the exposed wires.
The last couple of steps must be repeated (sort of!!) on the other end to get the cable into the panel. Once the wire is into the panel and the connector tightened, the wires simply need to be landed into their respective places. The black & red conductors will be put on the breaker and the white goes to the neutral bar while the ground to the ground bar. Put the panel cover back on and you are ready to reenergize the panel and test the receptacle! Never walk away from an installation without testing what you just installed!! If you test the appropriate voltage at the receptacle, you are good to go with the installation and can call it done!
We hope this has been helpful in explaining the general steps in installing an EV receptacle. What type of installation would you like to see in a video? Leave comments below in the comment section!

The electrical trade isn’t just strictly wiring things for a living. There are many facets and levels to it. In the latest episode of Electrician U, Dustin speaks to Master Electrician Chad German from Utah and Residential Wireman Matt Bergman from Texas about the different directions an electrician can go in the trade and where their careers have taken them.

Let’s face it. Electricians aren’t going to train themselves! Sure, there are pieces and parts one will excel at only by doing. But there are also many aspects of the trade that one must be shown how to do. As with many of us, Chad happened to be in the right place at the right time to step into training electricians. But honestly, Each and Every one of us who have been in the trade for any length of time, is at least a part time instructor. Whether its on the journey level (where you are showing the younger apprentices under you HOW things work and WHAT to do) to company/divisional leaders (where you may be showing seasoned trade veterans the nuances of higher-level leadership).
One of the things to remember when teaching others is that we are all different individuals. We take things in at different speeds and levels of complexity. So, our teaching style should account for those differences. In other words, we need to learn our crowd and teach to those levels. Some are perfectly fine with just doing the work, but there are MANY individuals out there that want to excel to the highest levels of the trade and must be challenged! Repetition is how the bulk of the learning and refining of skills should be taught. But more than just showing the apprentice HOW to do the task, we should let THEM do, with the guidance of a more seasoned veteran. If someone is just a gopher (hey, go get this or go get that), they are not able to put their hands on the tools/materials/processes to really learn. Nothing wrong with showing them once, twice, or several times HOW to do, but then they should be allowed to DO the task!
Licensing is another huge part of our beloved trade. By being able to demonstrate the skills you have learned at different stages of your career, and the ability to study and take an exam to prove it, is something that employers look for in their employees. It also shows that you are looking at the trade as a career, as opposed to just a job and willing to put the time and effort into yourself to become better. Whether it’s a residential wireman’s license, journeyman’s license, or a masters license, they are all steppingstones to bettering yourself! Having said that, licenses take time and aren’t handed out in some haphazard fashion. Each requires different time frames, but during that time you should keep your mind open, study hard, and listen to the veteran electrician’s advice and trade knowledge!
Another thing to keep in mind is that the electrical trade is MUCH more than just wiring receptacles and switches. There are MANY different avenues one can take within the trade itself. Maybe you have a knack for researching, quantifying, and being super-efficient. Then maybe estimation is the right place for you. Or maybe you are good with figuring out what jobs need what manpower and moving people/tools around like chess pieces to make several project schedules. Then maybe a superintendent is the right answer for you. Linemen, residential wiremen, service technicians, controls technicians; the list goes on and on. Our trade is so vast, there is certainly a spot for almost anyone; you just have to look for it and find out what is best for you!!
We hope this has been an insightful look into the different aspects of learning within the trade and where it can take you! Is there a topic you would like to see discussed on Electrician U?

When an electrician gets a job that needs to be built, how does that electrician know exactly WHAT they are building? Well, it usually because there are a set of drawings that shows them what to build! But what about residential vs commercial- is there a difference in those drawings? In todays episode of Electrician U, Dustin talks about the construction drawings and the nuances between Commercial and Residential.

A residential set of drawings shows- yep, you guessed it, a house! Generally, these drawings are drawn by an Architect and are meant to convey what the overall house will look like. There will be multiple sheets but, more than likely, the sheets will all start with the letter A (standing for architectural). The bulk of the drawings for a residential project will be centered around what the house will LOOK LIKE. There will more than likely be an electrical sheet(s), but these electrical sheets are general in nature only. As the architect has had much training in designing the LOOKS, they don’t know all the ins and outs of the NEC. But the electrician does! So, while the electrical sheets for a residential project show generalities and maybe a few specific OWNER requirements, it is up to the installing electrician (and the company that they work for) to design the overall electrical system for the residence.
Commercial sets of drawings are much different and can vary in size from a dozen sheets on a smaller job to several hundred sheets (and more) on larger projects. The biggest difference between residential and commercial drawings is that the commercial drawings are drawn by ENGINEERS in lieu of an ARCHITECT. So the entire MEP (Mechanical, Electrical, Plumbing) set will have Engineers stamps if you look at the sheet. In the electrical sheets, everything is laid out exactly where the engineer believes it should be placed and what exactly the installing electrician is placing there. Not saying that we wont move things (even engineers are not perfect and cannot foresee every issue before we get there!!) if required, just that the intent is spelled out in much more detail for us.
A commercial set of drawings will also have all of the different facets of an electrical job spelled out in much greater detail. So, you will have lighting drawings, power drawings, a single line drawing (one that shows ALL the gear/panels/transformers/etc. with conduit and wire sizes- electrician just needs to adjust for errors, voltage drop, or changes), grounding, data, security, fire alarm, and other systems. Device placement on a commercial project shall be as shown on the drawings whereas on a residential project the installing electrician shall install per the NEC while keeping the architects design intent in mind.
There is a long ongoing battle vs electricians as to whom is actually better- residential or commercial. Commercial electricians think they are better than residential electricians as the projects are much larger, the materials are tougher and more diverse, and the projects are seen on a grander scale. Residential electricians believe that they are better than commercial electricians since everything is spelled out for the commercial electricians and that residential is left to figure things out on their own. We will save this discussion for another day, but just know that both divisions of the electrical trade have their ups and downs!
We hope this has been an insightful look into the differences between a residential set of drawings and a commercial set of drawings as well as what the installing electrician is responsible for.
