An electrician has just installed the AC cabling for 2 parallel Multiplus II's and has only connected the L (Active) cable to the AC Out 2 connectors. He states the Neutral is joined in the Distribution Enclosure which feeds in & out to the Multi's.
This is what is looks like in the Multi's:
Is this OK?
If not, what are the implications of turning the Multi's on?
Note this is a house installation & not a mobile installation.
