I am going to build an oven in the upcoming weeks, my residential oven is not up to par with what i am doing. I have reviewed many of the schematics on the site and i am seeing that almost every one has a neutral wire in the circuit. some have the neutral wire going to ground and other to the socket.

I am in a shop that has many 220 Volt single phase sockets for welding, all three prong, 2 120 volt and a ground. due to cost i can not run a new line from the breaker with a ground and a neutral. Is there any problem with me tying the neutral line to ground in any of the circuts? or is there a circut floating around that does not need a neutral line?

Because my oven is going to be in a school shop it needs to be inspected after it is built. so i need to know that everything is up to Canadian code.

Thank you,
