Still not clear what OP's question is. The j-box looks like it's wired properly and is just a j-box, providing a place to splice the SO cord from the heater to the red cable providing power. Nothing related to a T-stat in this setup and nothing out of the ordinary in terms of configuration.

How long has the EMT been underground? If more than a couple years, I doubt you'l be able to pull anything through it, or even pull the old conductors out for that matter. Depending on the location, EMT won't last but a few years before corroding away to nothing, unless you're out in the...

Thanks for all the replies. I haven't been back to post, cause I've been too busy tiling! (and skiing) I decided since the directions, and almost all the directional videos, etc. recommended it, I went ahead and laid the backer down using thinset. I'm not sure what kind I used (modified vs...

Looking for some opinions from tile installers. I'm re-tiling kitchen in g/f's rental. Existing tile was placed directly on plywood subfloor. They did a **** job, thinset not spread well, tiles all cracking, areas with no thinset contact, etc. I'll be laying down 1/4" backer board on the...

Mine is just big enough to house the compressor, I think 30" x 30". It has a 28" door that I still need to install. I wanted to install an exterior-type door, but I can't find one in 28" size, so I'll just do an interior and put some type of insulating material on the inside, maybe acoustic...

Assuming code for ceiling mounted receps in garages is the same in Canada as it is in the US, which I suspect it is.

That's exactly what you need.

Potter & Brumfield K10P-11A15-24 $13 on Newark 24VAC coil, DPDT, 15A-1/3HP rated contacts https://www.newark.com/potter-brumfield-te-connectivity/k10p-11a15-24/relay-dpdt-120vac-30vdc-15a/dp/06R3605

Looks like a standard "ice cube" relay, made by dozens of manufacturers. Just match the specs (24VAC coil, DPDT and same HP ratings) and you can source one from numerous vendors/manufacturers. We use IDEC RH2B's, but you could use Omron, Eaton, Schneider, ABB, Allen Bradley, etc, etc, etc.

This thread is better suited to be in the electrical forum where you will get better response, and where this exact question has been hashed out dozens of times. Surface mounted flexible conduit is easy, but looks like **** and a hack job, IMO. Liquid tite is also damn expensive compared to...

I just use compression connectors in these instances so you don't have to line up a set screw, which necessitates the lock-nut. The bigger question is why was this even done in the first place? The flex line is converted to EMT a few inches from a j-box. Why not just run the flex straight to...

I used 6" wide Trex composite decking ripped in half. That keeps my OSB off the bottom of the floor.

The saw vintage matches the car in the background. But really, how good can that saw be, there's no laser beams on it! /sarcasm

Arc fault is not required in a detached garage and unless that 240v breaker is feeding a hot tub it's not required to be GFCI either. Unless your municipality has additional rules beyond NEC, these are not required.

All the bends can be minimized by using conduit bodies (LB's, etc) as you mentioned. There's a ****-ton of obstacles, walls, transitions, etc in that conduit run that will be a pain to deal with and possibly be an eyesore when you're done. Have you considered just running out away from the...

That's why they make lighted switches, which aren't code violations with lights/wire not installed in boxes, etc.

Switching the neutral is different than what we are discussing here and is NOT allowed and is a terrible idea for the reasons mentioned above.

So these are all local garages around the Ft Collins area? That is a cool idea! How did you hear about this?

By code, neutrals can be identified by white or gray marking, which means adding white tape to a gray wire is redundant and unnecessary EDIT: and per mm's comment in post 10, which corrects me, it actually is not legal, so you shouldn't tape them. Thank you for reminding me of that.

Last code cycle they added a requirement that all switch boxes need a neutral pulled to them, so the way you showed using a switch leg is no longer allowed by code.
