Issue:
Are the 4 pole PQ4606G Busplugs compatible with 3 phase / 3 wire Busway?

Product Line:
I Line II Busplugs

Environment:
Compatibility

Cause:
Forward and backward compatibility clarification

Resolution:
Yes. Both of these plug-in units are rated 600V, one is 3 wire and the other 4 wire.
4 wire plugs can be mounted on 3 wire busway where the neutral stab will not connect to anything in the Busway. Also, 3 wire plugs can be mounted on 4 wire busway.
