Just want someone to check my work before i power up this oven I built. Its for my vacuum former.
I added a thermostat to regulate the temperature. So the thermostat should energize the relay which will complete the heater circuit when there is a call for heat. I drew up the diagram from my head i cant remember all the symbols so its a little rough. I used a terminal block to split some connections with a jumper. I will also have a neutral coming off the terminal block which will run to the metal heater box. The plan is god for bid something metal where to fall in or i stuck my hand in there it would ground out and trip the breaker/fuse? or should i not bother to ground the box?
3 wire power coming in, power to relay, split off to controller
neutral to block which feeds 1 leg of heater and then neuthral to controller
ground to terminal block
2 white wires are for the heater 1 to neutral block the other off relay
heating element with thermcouple
gauge / thermostat
