Lighting Control : Site Lighting Relay Panel

[ElectDesigner]

Hi,

Im busy doing the lighting for a site, I have about 3 light circuits (347V,20A) that need to be controlled, i.e they must be connected to a photocell and timer/timeswitch.

Im not sure how the wiring will work, would I need just one relay panel with 3 relays connected to one timeswitch and photocell or would I need three separate photocells and timeswitches?

If you want them all to behave the same (turn on, off at the same time), one photocell and time switch will suffice.
