ASHP Supply & CU Discussion ThreadASHP Supply & CU Electrical Advice
Evening all,
Just after a sense-check before I commit & send the quote.
I’ve been asked to run in an SWA to feed a small CU that’ll sit inside an extension on the side of the house for the ASHP from a Tesla Gateway.
The customer has said the heat pump guys have asked for 2x 16A & 1x 6A circuits for the heat pump, immersion & control gear.
My plan was to fit a 40A C Curve MCB in the Tesla Gateway, run in the 10mm SWA (roughly 15m) then one of these (FuseBox RTB630302M DP RCD TYPE B 63A 30mA - https://www.fusebox.shop/products/fusebox-rtb630302-dp-rcd-a-type-63a-30ma) as a main switch in ASHP CU to satisfy the Type B RCD that Valliant ask for & then have 3x MCBs for the 3 circuits (1x 16A C Curve for the heat pump, 1x 16A B Curve for the immersion & 1x 6A B Curve for the control gear).
Does that sound about right?! I haven’t done an ASHP supply before.
