Evening, I've been asked to install a supply to a sprinkler system in a new installation that must be separate to the building electrical services. I.e if you isolate the building to work on the electrical services then the supply to the sprinkler pumps must remain live.
The only way I can see of doing this is to install the tails from the 200A service fuses to a bus bar chamber, feed the building panel board from that and also feed the sprinkler switch fuse from that. However, I am uncomfortable with the bus bar chamber having no isolation other than the service fuses
Is there an alternative way??
