I ended up with a bunch of steel city junction boxes without ground bumps. I’m going to mount them on a concrete wall. Are grounding clips the way to go or should I drill and tap? Or it doesn’t matter? Thanks

Can I use this fitting to transition from 2 inch pvc conduit coming out of the ground to rigid metal going up the wall? Or do I need to come up threaded and join with a threaded coupling? This would be a lot easier if there is not a downside. Do I need to seal the flexible rings inside the...

A lot of old eagle switches and plugs came through Restore. New in box. But doesn’t look like. current production. I like the looks of some of it. Too old to run or do you think it’s fine? Thanks

I’ve got questions about this 4 pole IMO brand switch I’m using as a disconnect for my solar array. I will have two strings at around 400 VDC and 9 amps paralleled at the array. Bringing in 400 VDC and around 18 amps on a pair of 10 awg wires. I’m doing switching example 2 In the paperwork...

Good morning, I’ve got eight 48 V lithium iron phosphate 100 amp hour batteries to be wired in parallel. Sample image below. What’s the optimum place to tap into this bank? I’d like the individual batteries to share the load as equally as possible. They will be connected with 4/0 wire and...

Good morning, I’ve run 2” conduit from the solar panel site to the shipping container. I’ve also run conduit from the shipping container to the workshop. Right now the conduit is in a trench roughly parallel to the ground. The pull angles are well under 300 degrees. The shipping container...

Are those compliant with NEC? Seems like TEK screws are not. But I don’t see much difference. I like to be in the neighborhood of code compliance. I think most of my boxes will accept a regular machine screw but I was curious. Thanks

I got this strange little metal door from habitat Restore. It’s heavy as heck. And about 6’2” tall. It has a piece of an inch and a quarter glass that’s fire rated. I guess it’s just some kind of industrial application where a 6 foot door is OK. It’s a standard width, about 3 feet...

I’ll be installing one or two mini splits before it gets hot. And a couple more later. I know I’ll need a vacuum pump. And this came up at Restore. I got it for $300. It looks new. There’s no oil in it, but I suspect the oil is appropriately drained after each use. Is there any way I...

This is my first time to run electrical wiring. One of the corners at my place is mostly solid. It’s where a 2 x 6 and a 2 x 8 wall comes together. I need to turn that corner to run romex. I can go up and over, but there are 20 foot tall ceilings. It would be a long trip (60’) but doable...

You may recall this house from the retaining wall thread. I genuinely feel sorry for my new neighbors. The first owners of this house. They purchased a couple of months ago. I know from watching the construction that the overall quality is abysmal. There were probably a half dozen...

I picked up a couple of very heavy steel doors at habitat Restore. They’re only 6’2” or so tall. And about 3 feet wide. They came with an inch and a quarter thick window insert that says it’s fire rated. I guess it’s for some sort of industrial or a commercial application where a short...

What water pressure would you guys recommend? I finally got around to picking up a gauge and I’m at 110 psi. I’ve got some regulators around here somewhere. I plan to leave it full pressure at the hose bib that intercepts the line before it gets to the shop. But would like something more...

I’ve got some exterior security lights I’d like to mount under the eave of a 3 story place. And I’d like to be able to switch them on, individually, from the bottom floor entrance. I can do it the old fashioned way, but that’s a lot of wire. I was wondering if there is a reliable way to do...

I’m sure I’m doing it wrong. I got this cord used and it just fell off the roll. What’s the secret?

I’ve got the Milwaukee 8 inch metal cutting circular saw. I was using it to cut my 11 gauge 4 in. square steel tubing. I bought this thing used, but in like new condition. I think it still has the original blade on it. I can’t make out much on the blade since it’s worn off. Anyway, I went...

I’ve got a landing I’m going to mount to a concrete wall. It has a staircase that attaches to it. The landing and stairs are from an old airport. The stairs form a parallelogram. That is, whatever level the skyway was at - the stairs with self adjust to that level. As you can see from the...

What would you call these bolts? And where would I find them? They have a fixed washer, a square head, and square nuts. Looks like 7/8 inch diameter, hot dipped galvanized. I’ve got eight and I’d like another eight. Thanks

i’ve got Armstrong commercial tile to finish out my living area above my workshop. It’s the solid composition tile, non-pvc. I think it’s something like 70% limestone. Very heavy At 60 lbs a carton. Color all the way through. I plan to install 2/3 of it on an Advantech floor (1.125” thick)...

I am routing AC power from an inverter located in a shipping container, using underground conduit, into my workshop. The run transitions from the inverter through 2-inch underground conduit and stubs up at a 10-inch-thick concrete wall. My plan is as follows: transition to 2-inch rigid metal...
