3 Lights on One Switch

Hello all.

I just want to run something past you all to see if this is safe.

My new house has 3 external lights, 1 500w Flood, 1 x 150w Flood and 1 x Bulkhead (which I need to replace).  A;ll three of these run to one switch and I was wondering if this is the correct way of wiring them.  Sorry I do not know the name of the circuit but a simple diagram of the junction box is as follows:


As above apart from one internal light with it's own switch then back to the Consumer box on there own MCB, (lights up and down are two seperate MCB's).   I cannot get into the bulkhead to see the bulb wattage but the max this must be is 100W so all three lights would be a maximum of 850W.

By the way, the lights have never actually worked as I have to change the switch as well as it is split, I moved in and turned off the MCB to save any accidents.  This was the main reason I checked the curcuit

My question again, is the wiring I show above OK or should I think about replacing it??

Thanks all

 

Hi both,  There is an earth to the floods as they are metal but not to the bulkhead as this is only plastic.  I also opened the switch and there is a sleeve on the black to signify the live, but if I do this I will most probably replace the wire from switch to junction box as it is only in surface mount conduit into the ceiling void (of course this will be with Brown / Blue wire and the blue will be sleeved.

My biggest concern was the total wattage on the switch, if you say this is okay then great.  Anyway she had one of her brainwave moments and 'we' could seperate the lights as one does not need to be on when the others are.

 

JP, can you whistle??  Cos your singing is rubbish

 

I'm going to split the lights anyway, 500W and Bulk head on one switch and the 150w on another.  150 cover just where the bins are so will only be used once / twice a week during winter months.
