[QUOTE="binky, post: 521932, member: 490"] I reckon is TT throughout, hence the 300mA RCD at the main board. To improve the reliability of the system, I would be looking at getting rid of that 300mA RCD - replacing it with a main switch, and RCDing the sub mains. I'm just trying to remember what the requirements are for the meter tails on TT entering a metal enclosure ie the dis board. If I remember correctly, as long as the tails are protected from the metal edges of the board then it is acceptable to do that. I was also thinking of getting rid of the 100mA RCD at the sub board in favour of RCBOs for the individual ccts. [/QUOTE]
