Hello.....on a recent job the homeowner asked that I install this device...

Here is the question..... I have a 400 amp main switch and 2-100 amp panels and a 200 amp panel feeding off a splitter.

If I parallel this device off the 400 A splitter will it do its job properly? Or is it recommended that he pick up a unit for each individual panel?

The literature says that this thing can only handle max 100 amps in series, but I'm wondering about 400 amps in parallel?

Any tips or advice would be appreciated.

Cheers!
