Hi,
Installing some electric underfloor heating in 2 rooms, both will total approx 3kw each (20m² with 150w/m² mats), each on a 16a thermostat with 2.5mm² running to CU on 16a breaker each.
However as there is limited space available in CU can they be connected to a single 32a breaker, then using 4mm² out to a junction box which then splits to 2.5mm² to each thermostat?
Cables will be clipped direct to surface in loft (roof timbers & raised off insulation), dropped down into room and buried in wall surface in suitable conduit. Heating in each room may be in use at same time.
Thanks very much,
