I am adding 1200 sq. ft. onto my shop and am currently laying out the electrical. I will have plenty of power and circuit breaker space for the addition, with two 100 amp subpanels coming off of a 400 amp main panel. I know what equipment needs dedicated circuits, where I need my 240v circuits...

Good day, all! I am getting ready to frame the inside of a steel building addition I made to my shop so that I can put up T&G plywood walls. I have had the floor sealed with polyaspartic so no bottom plates will have direct contact with bare concrete. Given that there won’t be contact with...

I was looking at a 20 amp circuit in my building over the weekend and discovered that there is an approx. 15’ section in conduit where the hot and ground are 12 ga. but the neutral is 10 ga. I have often seen the question “can I have a smaller neutral” but have never seen “can it be bigger.” I...

I am going to start working soon on framing in my lean-to sitting on a concrete pad and had originally thought about standard 16" studding, osb, wrap, some type of exterior siding, insulation, etc. but am starting to lean towards doing steel siding like the main building. For anyone who may...

Hello, I am in the process of wiring my 1500 sq. ft. wood shop and want to install a fair number of 240v outlets throughout. I have a couple of pieces of equipment where I already know what the recommended breaker and receptacle/plug size is but not certain how to size all of the rest that are...

Hello, I have a 1500 sq. ft. insulated steel building that has a lean-to on it (about 10' x 25') that I am thinking on enclosing. My thought is to insulate it and then either pipe in my HVAC or to vent the adjoining wall so that I don't end up with a sweat box. I won't be able to put a door on...

Hello, I have some three-phase woodworking equipment (two of which are 7.5 HP) that I am powering through a Phase Perfect converter (picture below). The manufacturer recommended just using twist lock plugs/receptacles instead of hardwiring into a disconnect but said I could do either. I was on...

Hello, I recently ordered/received a Phase Perfect 30 HP converter and am starting to work on how I will install and wire the unit. Questions I have is how to mount a unit that is 250# to a wall (I will probably use unistrut), outputting from the converter to a 3 phase circuit panel that then...

Merry Christmas everyone! Have a quick question before the grandkids show up for Christmas. I currently have 100 amps fed to my detached steel building using aluminum wire. This feed comes from my main panel at my house. I am having 400 amp run to my shop and will feed the existing 100 amp...

Hello, I am getting new metered power run to a detached building and will have several sub panels inside the building coming off of the main panel. One panel is for general lighting, outlets, bench top equipment, etc. I will also have a panel coming off of a Phase Perfect digital phase...

Hello, Bottom line, up front: If there is a minimal price difference between running 400 amp service instead of 200 amp service to a shop, is there a reason not to? We are running separate metered power to a wood shop that most of the time will typically be a one-man operation, but often...

Hello, Rented a Ditch Witch this weekend to trench out a 200 foot, 6" wide x 42" deep trench to lay 3" PVC so that the power company can later pull 400 amp service to my building. I had never rented a ditch witch before but everything went smoothly until near the end. The problem was that I was...

Hello, I have a detached 1500 sq. ft. building that I am converting one side to a wood shop. There is a 100 amp panel coming from the main that is on the opposite side of the building from where I am going to set up the shop. The panel is very lightly loaded and has more than enough space to...

Hello, I am rewiring my steel building and it would be advantageous to run line power into an outdoor light j-box on the right front side of my building, on to a switch by the man door and then to another light on the left front side. I have put in a solid 3-4 hours of internet searching and I...

Hello, Looking for some advice out there from the more computer literate. I'm not too shabby but this is a big enough project that I don't want to waste a bunch of time and money making mistakes. I am pretty convinced I want to bury conduit between my house and the barn and run fiber optic...

Sorry...this isn't actually in my shop but the sooner I get the project done the sooner I can get back to working on my steel building. ;) If inappropriate to post on this forum, I'll delete it. I framed in a pantry and a coat closet using some of the space not being used in our study. While...

Hello, I am still chugging along on my 1500 sq. ft. steel building running all of my electrical and, on the party half in the front, conduit to all the applicable places to route speaker wires, HDMI, DirecTV, etc. I am at the stage now of starting to close in some walls...last Fall I framed...

Good morning, I am getting to the point on my 37'x41' steel building (odd sized due to big Water Oak trees on property and another steel bldg that dictated where/size of new bldg) to where all my rough-in electrical wiring is done and I am ready to put up wall coverings. The front half of my...

Hello, Stopped by an acquaintance's house this weekend to look at his steel building project. He is about 2-3 months ahead of me so was interested in seeing some of the things he has done. One of the things that stuck out was his running either EMT or FMC into plastic boxes or, in several...

Hello, I have another circuit panel question somewhat related to the issue I had in the following thread: http://www.garagejournal.com/forum/showthread.php?t=356727. As discussed in the above thread, I have a detached steel building that has a new circuit panel inside that is fed from the main...
