Good morning,
I recently bought a Grizzly G9902 Mill (Bridgeport style) and a G750G gunsmith lathe.
I am a little perplexed about what gauge to run a circuit to each or both of them (shared). The previous owner has had them on a 30 AMP, 10 Gauge circuit, but they only call for a minimum of 15 AMP.
The Mill clearly has 14 gauge wiring at the forward/reverse power switch internals.
If I run a 220v, 20 AMP circuit to the machine will it be a problem with the wiring in the Mill getting hot, or overloaded so to speak? Will it possibly damage the mill since the 12 gauge wiring on the circuit is protected by a 20 AMP breaker?
Thanks, Joe
