Running of distribution cables

UKPN won't allow tri rated cables for CT chambers either.

Also check about isolators, you will need one as a single point of isolation probably above the new head before the ct chamber, not sure if you need one after it as it's a 20M run, then one before the new Busbar chamber. 3 x 200Amp isolators push the price up a bit! Best check with the DNO see what they want.

Why would the length of the run require an extra isolator? It would require overcurrent protection if it's over 3m certainly,
