Strange fault

[telectrix]

might need to fit a contactor/relay to switch the lights while putting a much lower load on the PIR/s

I think Tel has a very good idea there, you can buy a simple '1 module' 20 amp contactor for not much money then feed the coil from the linked PIR switched live, you can mount it in a simple plastic 2 module enclosure with a blank over the spare 'way' which will give you plenty of wiring space.

I agree. It's a good idea
