have in the past properly installed 20 Amp 120vac circuits to my main. I feel I have a good understanding as to how they work and are installed. I am going to attempt my first 240vac circuit for a new range. My existing range is electric but the wiring is old and since I have the wall open I have the chance to put in new. Here are the details of my new range.
Electric Supply:
These ranges must be supplied with 208/240 volt,
60 Hz., and connected to an individual, properly
grounded branch circuit protected by a circuit
breaker or time delay fuse (50 amp for 48" ranges,
30 amp for 36" and 30" ranges). The receptacle
must be a NEMA 14-50R device to accept the
4-prong plug supplied with the range.
The range is equipped for use with an electrical
supply which uses a separate grounding conductor
(4 wire system).
If this range must be connected to an electrical
system which utilizes a single conductor for ground
and neutral (3 wire system), the grounding jumper
at the terminal block must be connected.
The grounding jumper is located to the right
of the terminal block.
The model I have is a 30 inch so I need a 30 AMP circuit. Here are my questions
1- Why don’t I need a ground on a 240 V circuit?
2- When I install a 14-50R outlet can I put 30 Amp wire to it ?(This sounds wrong.)
3- What is the correct gauge I should use to hook this up?
