Sat Jan 21 - Craft Room Electric - 2nd Project Update Today

Okay. So I stopped working on the heater installation for today, here's what I got done.

I spent some time planning the wiring, then I installed the box and conduit. The wooden box for the heater is sitting on the floor:

Conduit
In this next picture the wooden box is attached to the wall and completely skinned:

More progress
There's enough room inside the wooden box for about a loop and a half of armored cable. That's enough to pull the heater completely free of the wooden box for service if necessary.

This type of in-wall heater is designed as a metal “can-within-a-can” with an air gap between the cans. It comes in three parts which are all leaning against the wall in the above picture.

The parts are installed from right to left. First the shiny silver-lookin' can is fastened to the wooden box. Then the black can (contains the heating elements, fan, and thermostat) fastens to silver can. Finally, the white face plate is attached to the black can. Easy peasy.

For safety there's two temperature limit switches inside the black can. This heater is a two kilowatt 240 volts. I can wire in a wall thermostat if necessary but I've never needed to do that for the half dozen or so of these heaters I've installed so far in my life.

Oh. By the way, I'm no cabinet-maker. The wooden box is just a solid box that's fancy enough for an unfinished basement.

Darn it! Darn it to heck and all the way back. I just did a final review of this article and was getting ready to click the “publish” button when I realized I created a wiring code violation. I'm not sure what I'm going to do about it, I'll think on it overnight and try to come up with a solution. Off the top of my head I can't think of an easy fix. So much for being in a hurry. Rats. I gotta re-think this whole thing.
