(Electricians)Wiring up a 240v garage heater

I dunno about your garage, but my garage was woefully underpowered originally.

Running a compressor and ANYTHING else would trip the 15 amp breaker.

I ran a 10/3 wire with 30 amp breaker and added a large receptacle with one of the receptacles being 240V,

Now i can run my mill, lathe, compressor, flood lights and still be good!

All on thats 1- 2 pole 30?
 
Oke I stand corrected, while #12 is good for 30A your max over current protection on #12 is 20A.
 
I have adequate 120 power in the garage to multiple plugs. Never had a problem running compressors and saws etc. I really just want the heat. My panel is basically adjacent to the back wall of the garage so future runs are easily done.

Thank you.


Edit : They only introduced that new code in 2012 to address the ridiculous derating rules when using multiple conductors in conduit, typically in commercial and industrial settings. AC90, Romex, and the usual cables still go by the standard amperage tables we've been using for years.

If you ran a 3 conductor cable you could upgrade in the future to a small pony panel just for the garage but it sounds like you're set as you have it.

No, the 15A single as well...

NOBODY runs all those things at the same time....well maybe an actual shop does, but i dont run my lathe while running my mill, or the compressor....

but now i dont have to constantly switch plugs....before i had to run the compressor OR the lights on that single 15A breaker...
 
anyone else notice that whenever sparkies or wannabe sparkies get involved it turns into a pissing match?
gotta be an occupational trait or something

It only turns in to a pissing match when incorrect information starts to get thrown around.

I always hear people ***** about the "know it all electricians." Usually the same people who insist their totally wrong and outright dangerous electrical is perfectly fine.

I was more curious if you had a 30 amp sub panel or if you 15A plugs also tired into that 30.

If you only knew how many electrocutions, shoddy wiring jobs, and fires from homeowners and Joe Renovators, I've seen/heard over the years from "wannabe sparkies" as a result of misleading and incorrect information, as was even presented in this very thread.

Wiring is not a hobby.

My aunt just had a new electric furnace and water heater hooked up, it's a pretty sad sight.
Considering the whole ceiling is exposed all the way to the breaker panel, a good guy would have run the wiring the same way as the rest of the correctly installed wires, instead of stapling it lazily to the bottom of the rafters in a diagonal line.... :banghead:
Now i can't just slap the drywall up as planned, I knew i should have run the lines myself, but the dude seemed competent at the time... Fail.
He also left the old lines swinging from the ceiling, for me to deal with i guess. :confused:
 
I'm surprised nobody's mentioned that any electrical work done without a permit renders your home insurance null and void. (laws changed two or three years ago)
The only exception is a liscenced electrician replacing a light switch, or a receptical in his/her own home. Anything that's new, requires a permit.
that being said the american nec says 14awg is good for 20a. canada's cec says differently. There's safe and then there's safe.
Does it work and does it stay cool? If yes your good to go.
If your not following the law who cares if it's code.

What is your actual experience in this?

Do you realize licences electrical contractors perform work all the time without a permit when they really should have one.

When does esa make you rip something out and redo it? When it doesnt meet code.

Ya some really solid advice there.

In ontario electrical work must be performed by a licensed electrical contractor. They are the only ones who can pull a permit. The only exception I believe is home owners in their own home. But they still need a permit. not sure if this has changed never been involved in that.

You seem to doubt your own assertations as do others.
 
sorry. laws changed about what work can be done without a permit.

Insurance companies have fine print in their own policies that say they don't have to pay.

insurance companies don't want to pay if " illegal work has been done " - Reason being, if the home owner installs a penny instead of a fuse, or the home owner overloads a circuit by adding an extra ten pot lights, and the house burns down... the insurance company shouldn't have to pay.


The electricity act follows the C.E.C.

somewhere in the CEC it says all electrical work must be preformed by a liscenced electrician or an apprentice - can't find it right now

from CEC 2009...
Code:
2-005  An application for inspection not required
Notwithstanding the provisions of Rule 2-004, an application for inspection is not required
(a)     in an owner-occupied single dwelling for the installation of replacement equipment (such as fuses, receptacles, 
luminaires, general-use switches, utilization equipment, transformers for extra-low voltage circuits or equipment 
in extra low voltage circuits) if the equipment being installed
(i)      is installed by an electrical contractor licensed in accordance with Regulation 570/05; 
(ii)     is installed in a branch circuit having a rating not exceeding 30 A and 130 V;
(iii)    is interchangeable with the equipment being replaced in function, electrical rating, size, and weight 
without having to change any part of the branch circuit; 
(iv)    is installed in the same location as the equipment being replaced;
(v)     is approved in accordance with Rule 2-024;

Your not understanding

Permit or not....a great tip off to an insurance company that work was done illegally is work not meeting code.

Your suggestion to ignore code if your not going to get a permit is stupid.

BTW, how do you know the OP is isnt pulling a permit?
