13A fuses for 16A immersions?
45A DP switches - wouldnt 20A DP do and be a bit cheaper?

The 13amp fuses might well last for months, but none the less they are
not appropriate, nor is the spur unit rated at 16amp.

Two separate circuits from the DB would be a better way to it, each
rated at 16 or 20amp. Failing that, a 2way DB mounted at the far end of
the 32amp feed, with a 20amp rated DP switch for control.
