[QUOTE="binky, post: 551478, member: 490"] Correct but TT systems usually have 30mA RCDs downstream of the TD unit, its those you don't want to be sharing with the solar. There's some debate about the need for a TD if you have a full board of RCBOs, or all circuits covered by shared RCDs, effectively it's only protecting the meter tails from shorting to a metal board. If said metal board has clamps for the meter tails, and full board of RCBOs, then I believe it can be eliminated. [/QUOTE]
