G73 Heater with Power Cord

[elky1953]

Hi,

Recently purchased my G73 Heater for the garage and about ready to mount it and wire it in. Here is my situation.

During a new home build I had electrician install a 240V 30Amp female receptical in the garage wall (with 30A CB at the CB Box) with the intent on the future purchase of the G73 Heater.

Now that I have the heater I want to mount it about 2 feet from the electrical outlet on the wall 7' from the floor and I want to use a power cord.

- purchased 4 feet of 10/3 awg wire.
- purchased male recepticle 240V 30Amp.
- purchased 1/2" right angle fitting for heater knock out.

My questions are; is the power cord setup okay to use ? Is there any danger here with overheating the cord ? The power cord jacket seems to be quite thick and is rubber. Is there any disadvantage or should I do hard wiring?

Thank you for your answers.

Some things I'm thinking.....what type of wire did you get? I don't think you can use regular Romex/NM with a plug but your description sounds like you got SJOWA or similar. The fittings need to be listed for use with the type of cable. The heater probably has specifications as to what insulation it wants on the supply wire, such as 90C, 105C, etc.

Some appliances are not meant to use plugs, i.e. making them a 'cord and plug connected' device.

Here's how mine was before the move - #10 cable, twist lock plug.

Thanks to all for your responses.

Thanks porcupine, I bought a 4 ft cord from Home Depot, 10 gauge, 3 conductor. It has a black rubber jacket about .100" thick. Says 600 volts on the side with -40C to 90C. Each 10 gauge is stranded with white, green, and black jacket. I agree about the fitting and making sure to have the proper one for this cable. Fitting needs to grip the outside jacket. I don't think the one I got allow passage of the O.D. of this cable. Guess I'll need to find a better one.

I used the same 10/3 600v cord from HD on mine.
