As a catchall... no, with your current (pun not intended) level of knowledge, I'm afriad it is a no nowould you say doing the CU is deffinately a no no?
i was going to attempt it but the more i look into it the less i feel like it.
i've done wiring before but only to an existing CU to a spare mcb.
Unfortunatly earthing is pretty important, the problem with TT systems is that the earth is of a much higher impedance than a TN system, incidentally, have you asked your supplier if they can provide a TN earth?its just the earthing thats throwing me.
surely there is work i could do comfortably to save a few pennies in a rewire i.e. chasing out, routing cables putting back boxes on etc?
