Boiler panel controlling a 3 phase grundfos pump. Pump was tripping thermal overload...
Pump replaced for a single phase grundfos by engineer etc...
I was asked to convert the control circuit to single phase which I did.
But still tripping on the thermal overload.
Set it slightly higher for...
Split phase supply L1+L2 on one phase and L3 on another, EB has 3 phase 4 wire incoming but they’ve been out to check and said it’s split phase, what would you put on certificate? 3 phase 4 wire or 2 phase 3 wire?
I went to some holiday cottages today, the main supply in was 3 phase however only 2 of the phases were used. The L1, L2 and Neutral cables were wired into a three phase meter, then coming out was L1 and Neutral, L2 and Neutral to create two single phase supplies which were divided off using...
