S Korea Electrical Distribution

[nhee]

Is anyone familiar with the 220 VAC/60 Hz distribution system used in Korea? Specifically - would a 220 VAC fixture require single or double pole switch.

I am not familiar with the Korean system, but you generally only want to switch ungrounded conductors.

Therefore, if this is a 220-volt to ground circuit, one pole is needed. If it is 220-volt line-to-line, than a two pole would be needed.

Agreed.

I guess my question should have been, is the S Korean System 220 VAC L-L or L-N?

It doesn't matter, use one pole for control, two pole for disconnect and control.
