Friday I fitted a 40 Amp contactor to drive the actual streetlight load, so the master relay only has to drive the contactor coil load. (± 80 mA).
Also I checked hour meter readings and reinstated the lightcell which functioned allright.
To complete that all was OK, I scoped the job @ 23.00 hrs as part of streetlight patrol. and had a chat with the Pizza shop for the shutdown at 24.00 hrs to take the generator off while repair crew replaced the damaged cables.
