i'm doing inspections on some year old d.b's. they were prewired by a switch board manufacturer. it is a lighting board with loads of finder relays and bases.
1st of all the bases are burning out . the relays are 16amp running about 11 amps max. up to 20 double 5 foots on 1 relay.
then i moaned about the internal wiring colours to the relays from the din terminals red,white and blue for live and neutrals. the consultants and db manufacturer says that its allowed if the wiring is marked with a no.
