A few years ago we were installing a 16mm SWA cable to a control panel at a factory. The panel controlled a large pump to boost the pressure on their sprinkler system as the water company could no longer guarantee the pressure .
Their insurance company sent us a set of Regs to do with fire and sprinkler systems etc. and one bit read; The cable should be connected to the main switch , have no means of isolation or fuse links . We refused to connect it like that as our 40 mtrs of SWA would have been connected to a 500 amp switch fuse !!
Told them it was connected according to the electrical regs and we were not prepared to alter it. We connected to a 60 amp switch fuse and had a big label made to stick on it.
What would you have done ??
