External Lighting Circuit

Savdar1810 · Jan 30, 2019

Good morning guys, looking for a bit if advice.... I have 3 external spots lights (single phase)

[ElectriciansForums.net] External Lighting Circuit

that are ran off contactor and timer... there was no diagrams or existing circuit to follow... could one of yous maybe tell me if this circuit I quickly drew up would do? Thanks a lot

looks OK from here.

Nothing you'd change in it? I have only been practising this trade for 3 years....I am a mechanic to trade but decided I wanted a career change a few years ago so i done my HNC in electrical enginnering and a few other city and guilds and 18th Edition and started working in renewable energy as supervisor of wind farm... not 100 percent confident yet so hence why I am asking for advice.

Drawing not the best tried to simplify it as best as I could as you can see

Why not use a time switch, either standalone or DIN mounted?

Yeah I have a time switch in place, it's a really old one tho and there's only 3 wires coming from it tho .. L&N and I am guessing the other one is the signal wire which will send 230v to the coil...there's no others. There's no symbols or anything on it either or instructions. Hopefully the circuit I drew earlier and posted should do?

What is the purpose of the timer?

Post a picture of the time switch, you may not need to use a contactor if it is suitable to switch the load

Agree with above, as all the circuits are effectively controlled via one MCB I assume the loading is not very high, so do you actually need a contactor?

p.s love those space invader light fittings, very retro

Just to bring on contactor at certain intervals

As you say it is quite old is it a round mechanical timeswitch with a black base and a clear plastic cover?

No it's got a LCD display still looks quite old tho, soon as I touch it all the writing just rubs off, it's completely gooked... might just replace it with a new one as I need to rewire the full circuit anyway.
