Hi guys could you help me please i have been given this question but i don't think it is right:
An A2 radial circuit is wired in 4mm 2 thermoplastic twin and earth cable. It is 23 meteres long. The circuit has on it 4 twin 13 amp sockets, Protection is by a 30 amp BS 3036 semi enclosed fuse, Ze for the instalation is 0.6 ohms.
socket 1 is 12 metres from the consumer unit, socket 2 is 6 metres from socket 1 and socket3 is is 2.5 metres from socket 2
Calculate the r1 & r2 value at each socket outlet
Will the protective device be suitable
could you let me know what you think the answer is so that i can compare mine
Thanks in advance
