Is it compulsory to record the geyser serial No: in a coc?
And , when labling DB's ,is the main DB DB1 or should yor first sub board be DB1 or is it main DB and first sub board DB2?
What is the differance between a local switch and main switch?
If your meter box is outside the property and u have a second box in the property that feeds the main DB, is this your local box?
Thanks, appreciate the info Andy and you guys!
