Been asked to look at an electric UF heating system.
As yet it is laid but no connected and no supply is present.
There are two mats at 1600w so total 3200w, 14A.
My intention is to run a feed off a 20A RCBO via a 20 DP isolator to the thermostat.
Run in 2.5 T&E, clipped direct total <10m
However the MI state to run direct off a 32A breaker (No iso) which would mean 4mm cable which will not terminate in the thermostat.
Any thoughts.
