30 amp / 12-3 wire question


Recommended Posts


The answer to the original question is quite simply "No."

Write it up - The yadda-yadda draws a 30-amp load and is only wired for a 20-amp load; if this isn't corrected the wiring will overheat and might even start a fire. This is a fire hazard; get an electrician to re-wire the circuit to the yadda-yadda now."

Actually it depends. What kind of appliance are we talking about?

If its a central air conditioning compressor that has a 30 amp max. fuse/breaker rating but a Min. circuit ampacity of 18 amps. it's fine.

Now if your talking electric water heater... No good replace the wire.
