My New House & Workshop

[Jim Oaks]

I made a little more progress. The conduit is installed and the wires are run into the breaker box. I stripped the jackets off a few to run them, and left a section at the bottom to label them. From here I'll remove the jackets as I install the breakers.

I still need a GFCI breaker for the shop outlets. They're required in a 'garage' and I've shocked myself a few times from faulty cords on old power tools, so I figure I might as well follow the rule. The only other place I have GFCI is the restroom, and the other sink I installed, but the restroom got a GFCI outlet and the outlet by the sink connects off of the GFCI outlet.

I got two GFCI breakers for when I put power in my shop (since it was actually inspected) and it was all the outlets I had at first. Every now and then my puny little Delta 8" miter saw trips the breaker with the inrush current... it's really annoying. The rest of the breakers I put in are standard ones... I get it and just try to keep good cords on everything...

When I built my grill guard and sliders, I used my Lincoln 110V welder hooked to the GFCI outlet in my kitchen with an extension cord and it never tripped it.

I have an outlet back in the corner of my shop for my compressor, and an outlet by the door that I'll use for my 110 welder that are on the same circuit. I know what you're thinking, the compressor should be on its own circuit. Well, in a way it is. I don't use air tools. I only use the compressor for airing up tires and painting. When I'm not doing those things, it's shut off. I don't weld and paint at the same time. If for some reason I wanted them both going at the same time, I'd just plug the welder into a different outlet. But I like having that one outlet by the door that's on a separate circuit then the other outlets in the shop. I will probably use a GFCI receptacle for the outlet at the door. For now, I just have a regular outlet there because this GFCI crap is expensive.

Inrush current from a device should never trip a GFCI. They are designed to trip when there is an imbalance of current between hot and neutral which indicates that current is flowing to ground some other way, such as through your body.

In theory yes. In practice they can give a lot of nuisance tripping.

There are rules in the code that let you run without a GFCI. I have used them at work before.

One example; Outlet is for a critical application and is mounted to discourage regular use; Example your chest freezer. You do not want the power to your chest freezer tripping out all the time. They make receptacles that have one socket instead of two. So if you use that, and they also make a metal bracket that covers the freezer plug and locks it in place, then that is allowed.

If you had a single receptacle like that feeding your air compressor, and it cannot be used for regular plugging and unplugging, you can run it without a GFCI. GFCI is a people protector. Keep the people away and have a good reason for not using it, and they will allow you to run without it.

On our well pits at work we have 110v recepts and have chlorine feeder pumps plugged into them. The state inspector wrote up that the recepts needed to be GFCI. I considered chlorinating the water for public use critical. I knew in that damp well pit the GFCI would trip all the time. They state in the code if the recept is behind lock and key and only "trained" personal use it, it is allowed not to be GFCI. I had to give the safety guy the excerpt from the code, and I have not heard anything about it, and that was several years ago.

I won't argue against nuisance tripping. But inrush current isn't that.

Persinally, I hate GFCI devices even though I am pro safety. Most GFCI devices, in my experience are cheaply made. I also believe the design trip threshold is too sensitive. But, we have to attempt to protect idiots frim themselves.

Cuz da gub'mint says so.
