CU Change for assessment

[liam b]

Ive changed a CU for my assessment and rewired the upstairs lights due to no cpc,

will the assessor want to see calculations for cable size and voltage drop for rewiring the lights?

and will he want max demand/diversity calculations for the CU

and on the inspections, what happens if a box gets a 'x' do i need to put it right?

thanks in advance.

NO, but he will want to know if you know how to work it out and if you dont how you can find it out..
big hint is have the PC on and take him to TLC website and click technical section...!

and will he want max demand/diversity calculations for the CU

probably not

and on the inspections, what happens if a box gets a 'x' do i need to put it right?

you will be expected to carry out a handfull of tests on your work to prove to him you can do them..! they normally very helpful and if you do get a bad mark that requires attention they will tell you what you need to do and let you do it there and then if time allows or to take photo evidence and send to them.

thanks in advance.

hope this helps
