Reading the article in PBO 429 on the reply to 'How to make a switch'.
It seems to me that it is extremely dangerous to potentially bypass the battery isolator switches with relay contacts especially if mechanically latching relays are used.
I realise that this has been sugested to enable instant revertion to the original installation but this will not happen if the relay contacts remain closed.
Battery isolation switches are for one main purpose which is to isolate the batteries and should be connected in series direct in the line from the battery, irrespective of how many fuses are in the circuit.
There will of course be exceptions such as the relatively low power always on fused supply.
