Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only

Sergio Fernandez

Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only.  But what if the dwelling has 3 phase due to size of house or for Solar PV or EV (Electric Vehicle or HP (Heat Pump)?


Eg 

Single phase safe isolation 3 point test at 230v AC nominal

3 phase 10 point test but at some point phase 1 to phase two at potentially 400v AC


As always please be polite and respectful in this purely academic debate.





Come on everybody let’s help inspire the future
