Multiple Exterior Lighting Circuits

[Danny124]

Hi all,

Having a brain fart...

Looked at a job today, have multiple exterior lighting circuits (4x MCB'S). Can see why there is multiple, as previous electrician was worried about cable lengths etc as the property is quite large.

But seem to have multiple Photocells and timers controlling, with outside switch for over riding specific lights.

Client doesn't like 4 photocells on side of his house, and having to reset/change times on 4 timers.

Any ideas how to incorporate these 4 circuits into one timer switch, possible PIR's and over ride switch.

I'm thinking contactors, but can't get my head to think properly on this one.

Thanks in advance guys.

Cheers

The contactor route is preferable, not least because as already stated you wont lose all the lights with a single fault. The point I was making on the single circuit is as stated above, the volt drop would be calculated on each separate line and the highest would apply, not all four added together. Either system could be used, conversion to a single circuit or a contactor, a contactor having the advantage.
