Aurora make a 1 gang 600w dimmer which requires no de rating and fits well in a standard 25mm knock out box also comes standard with a snazy night light which requires no N conductor to work which is nice .
I wld terminate it now so it can be tested and labbled in the CU so as not to confuse matters in the future new owners etc cld presume the circuit faulty if it is not connected or evan connect it with out the testing it needs before its used etc..
Change all your fcu for one multi gang box mk or something nice and tidy always a good idea to have cooker run just in case you change to a electric hob .
I had main bonds out for Zs, and also I tested it with the soft facility, am i right in assuming a calculation of Zs is best for the reading to be recorded on EIC ? or is there other precautions i shld take into acount before accepting the result?
