| I have two ovens (Miele h4080 240/20 and H4880 240/30). They are not a single combo, but have two separate wips. I have wall open to studs and do not know what to wire.
My preferred way would be to run #6 240/50 4-wire line and connect two receptacles. What the code requires. Do I have to run 2 separate lines? Had these ovens were a factory combo - they would have 1 plug, but they do not make a combo like that with these two? If I can have one 240/50 line - how do I connect two receptacles or does a dual receptacle exists for #6 cable? |

| Each appliance must be on its own dedicated circuit. How would you have overcurrent protection for the 20A and separate 30A appliances with a 60A breaker? |
|
| Sounds logical - but I think over-current protection is more for the circuit wire than for the appliance. Appliances usually have their own over-current protection. On the other hand when there is double oven combo unit comprising 2x 30A ovens it operates on a single 60A circuit panel breaker protecting single line. Confusing enough - forget logic forget physics - what the law requires? |
|
| Sounds logical to me. I don't have a code book nearby. Hopefully someone else can comment on code requirement. |
|
| What do the installation instructions for the ovens say? If they say 'require' for a separate circuit, the NEC says you must follow the manufacturer's instructions. The issue is is the appliance wiring sufficient to carry a fault current to trip the larger breaker? The internal wiring needs to be able to carry at least the breaker rating to avoid the appliance conductors acting as a fuse before the breaker can trip. |
