Appliance wiring
 

Just a question out of pure curiosity.

New dishwasher installation, manual calls for a 20 amp breaker. No problem,
run 12Ga/2 (with ground ) Romex from breaker to J-Box, Run 12Ga/2 (with
ground ) BMX up to dishwasher. Open dishwasher electrical cover and it has
16Ga wire?????

So if code requires 12Ga for a 20 amp circuit how can the UL/CSA labeled
Kenmore dishwasher have 16GA wire for the final connection. Same thing with
the garbage disposal system.

Any thoughts on this one?

Appliance manufacturers don't bother with things like NEC requirements for
ampicity. Look inside your electric water heater, same thing. You're
suppose to run #10 wire on a 30 amp breaker to it, just to find that your
tying on to 12 or 14 gage wires inside. It's UL listed that way, so it's OK
to use it.

The appliance circuit from you panel to the appliance is usually a longer distance than the smaller
wires within the appliance. And besides, the smaller wire probably has a greater heat resistant insulation.

Perfectly normal and safe. It is a totally different enviornment from the
feed cable. Appliance wire is usually totally contained in the metal
appliance shell and usually has an insulation which will stand higher
temperatures.

Hi,
Consider distance from breaker panel to dish washer for one.

Most appliances are wired with 105 degree or higher wires plus they are not
sealed in a cable. House wire is 90 degree, some is 60 degree.

The breaker is there to protect the house-wiring (and the house) in
case of overload.
Not the appliance.
