Is it permissable to have two feeds into a grid switch?
I'd like to combine 6 ways (one 20A feed) with 2 ways (second 20A feed) in one 8 way grid box.
I'm asking because I can see that you would need to trip two MCBs before opening the grid - ie no single point of supply.
NB I'm NOT proposing any cross-connection between the "6 feeds" and the "2 feeds" so electrically it's OK - just a possible future safety issue if a switch replacement is needed.
The total load for the combined 8 ways is over 20A - hence the need for 2 supplies.
Thanks
Mike
