Re: Connection at pole/plinth fuse

Re: WoEF

I don't think a WOEF is classed as an inspection, but it must be done by a person who is authorised to inspect mains work ESR 78 (1) (a).

as far as been PEW, yes., ESR 65 (6) tells us certification (which is what a WOEF is?) is PEW, but does not require a COC.

Re: Lockable main switch at switchboard connection - 4777.1 2005

the way I read it, is the switch between the output of the inverter and the switchboard it connects to, the switch doesn't have to be in the switchboard, it could be beside, above or below, or at the inverter.

As an alternative, the contactor could be installed in an enclosure in the ceiling space above the kitchen. Or in a corner of a kitchen cupboard, depending on the physical size of the contactor you may even be able to squeeze it in to the flush box.
