2 wire heater to 3 wire plug??
Hi there ,
I have garage heater and it has 2 load wires and a ground the plug is a leviton that has 2 loads /1 neutral and a ground. How do I wire the heater to this plug? Do I wire up the 2 loads and ground and put a marette on the neutral on the power plug ??
This is the heater I have:
6,000W Shop Heater | Princess Auto
this is the plug I have: Norwood | Stove Cord Kit | Home Depot Canada
Thx

Your heater requires 25 amps at 240 volts and the cord is a 40 amp 250 volt 4-wire range cord. I wouldn't add a cord at all, but would hardwire the heater to a 40 amp crcuit with a 60 amp fusible disconnect fused at 35 amps. The manual calls for a 35 amp breaker which I doubt you'll find.

Connect the ground wire in the heater cord to the ground pin on the plug. Connect the other two wires in the heater cord to the load (hot) pins on the plug. Leave the neutrl pin on the plug empty.
Be sure to use a 40 amp plug and receptacle set with 8 or larger gauge wires to a dedicated double wide double breaker in the panel.

great thanks very much Allan for the reply. I was thinking that leaving the neutral wire empty was the way to go but was not 100% My installation is exactly as you've described.

my selection is to use the plug option. Any thoughts on how to wire heater to plug?

that sounds very interesting as well, I'm not an electrician or HVAC guy, but perhaps you can explain how this is done? Im interested and want to be safe.

Well, briefly put, if some other device was needed that took a lot a of juice then I could unplug my heater and plug in the other device, well that was my thinking anyway. Also like the idea of being able to unplug something when things go wrong. that being said the sub panel is new idea in the garage I decided this afternoon to go this route and have the panel mounted but no power to it though the power is there in the form a 6/3 gauge cable running off the main panel from the house off a 40 amp breaker.

great thank you for the clarification. Are there any special instructions when wiring the 6/3 feeder to the sub panel? I have not done this before I am confident I can do it properly with some guidance.

Wow that is a lot of very useful information. Thank you very much!!
Bonding screw does not appear to be on the Neutral bus, but was found at the top of the panel? see picture of panel attached.
4-wire feeder yes I have this installed:
Southwire | Underground Electrical Cable – Copper Electrical Wire Gauge 6/3. NMWU 6/3 BLACK - 150M | Home Depot Canada
panel:
Square D CQO116M100C60
Auxiliary ground bar is included but not attached to the panel

The cable appears to be correct. Not sure why the picture shows a gray wire in it. As long as the wire is really black not gray that is okay.

The stuff I have highlighted blue, is the correct for the neutral bus? If so do I remove the green screw from the neutral bus?
Just a little confused re"Install the ground bar and remove the green bonding screw from the neutral bus and throw it away, the neutral must be isolated from the panel can and grounds."

Number 1 is the bonding lug for the equipment grounding conductor in the supply cable.
Number 2 is the equipment ground/neutral bonding screw. Remove it and discard.
Incoming neutral will connect to either A or B to a screw of sufficient size for the conductor. Both A and B are neutral buses.
Incoming (from supply) ground connects to the lug labeled 1.
C and D are equipment grounding buses. Connect the bare copper (or green insulated) conductors of the various branch circuits to these.
