Last night I went out to my garage, and when I went to open the door I realized that I had left my keys at work. I couldn't find my spare keys, so I grabbed a random key that looked up to the job and used it to bump the lock. I'm no expert in lock bumping, but I was still able to make it work in...
15 kW/240 V=62.5 A
Also, the safe working load for a breaker is 80% of its rating, so 48 A is typically the max for a 60 A breaker.
Working back from the figures you gave us:
59.7 A / 80% = 74.63 A
Seems you'd be more suited to a larger breaker.
The walled of portion of my shop exists to create a dust free zone for the machinery in there, sawdust won't be a problem. My worry with those ceiling mounted heaters is that there is a lot of energy being dissipated in such a tiny space. If the fan dies and the over limit switch craps out, then...
Well, I'm sold on the Oulette heaters. The low-watt-density models are exactly what I was looking for. Thanks, jvitez. I can get them through a bunch of local electrical supply places, which are way more fun to visit than Home Depot.
They were also the star of a "How It's Made" segment...
Charles,
2 Linotype machines, a printing press, 12x36 lathe and a milling machine. The ceiling fan is a good idea.
The climate is quite dry here, and I haven't had any trouble with condensation, even without heat at all, fortunately.
JoeFin,
If I'm being realistic with myself, I don't get a lot of free time to be out there, so I won't be keeping the room at a comfortable temperature for very long compared to how long I'm just keeping it from freezing.
I spoke too soon. "Global Commander" heaters are made in Canada. Well, Quebec. Close enough. And they're much cheaper than the fancy pants proportional units... But the idea of proportional control actually appeals to me... Still interested in hearing about baseboard alternatives, though.
I have a 12x17 room at the back of my garage that I need to heat.
The good: The room is surrounded on three sides concrete block walls, backed by dirt right to the top. The fourth wall and ceiling are well insulated. It's about as close to a cave as a person can get. I have around 12,000 pounds...
Fernie? Odd example to use. Having grown up in Fernie and moved on to warmer climates, I'm always surprised at how under-built things seem in the warmer areas.
I grew up in a similar situation, so the concept of "hiring someone" is a still a difficult one for me. My dad always had a construction project on the go. The only thing that he'd hire out was the excavating, for that he'd call on Henry or Bill down the road. Everything else was done my by dad...
They're 4x8 sheets, it looks like they're white or off white. I haven't seen them in person, I found them through an ad posted to the local classifeds site.
The timing is good for me. 3 out of 4 of my walls are below-grade concrete block walls. I've lived here two years, and the only time I've...
A local hardware store is selling 5/8" 'DensShield' tile backer board for $10 a sheet (looks like it's a discontinued product). As I understand it, this is drywall with fiberglass backing instead of paper backing. $10 isn't far off what I would pay locally for a sheet of 1/2" drywall. What are...
This is a great opportunity to get some practice with a hack saw. My dad wouldn't let me use anything but a hacksaw, and my first cuts were terrible. But, I'm not 13 anymore, and I can follow a line and make square cuts with ease with a hack saw now. It's a skill that you shouldn't be without...
