You are now suggesting that MCBs need to be spaced to prevent overheating. Whilst that might be true at very high ambient temperatures in particularly demanding circumstances, why do you think such spacing is NOT designed into CUs or any other circuit protection system? In a domestic CU, the average consumption is very small. How long do you think it would take to make the whole box at an excessive temperature, given the very small overall dissipation of the very few MCBs?
David, I pointed out in an earlier post that manufacturers may say their CU is only suitable for fractional loading
