[QUOTE="NozSpark, post: 75387, member: 601"] That would be unlikely. 16th ed CU's (split load) had a main switch that isolated some circuits and also fed an RCD which protected some more circuits. 16th TT CU's had a 100a / 100mA time delay RCD instead of a main switch 17th ed CU's (twin RCD) have a main switch which feed 2 seperate RCD's which protect some circuits each [/QUOTE]
