Mercury lamps!

[ChrisRogers]

I am about to install one 80watt mercury lamp outside on its own circuit. Its fed by a 10m length of swa and Teed off to a 10m length of 2.5mm swa. The T is so i can add another light later on.

My question is as this is a dedicated circuit, what size breaker should i use? i know the lamp in only 80w but i don't know if it was high start up current or anything I'm overlooking.

for those curious the cable run looks like this:

CU-----4mm SWA--------Junction box for optional light
|
|
2.5mm SWA
|
|
Junction box for 80w mercury lamp


The lamps shall be connected the the junction boxes via artic blue cable, and appropiate glands used.....

edit: my pic doesn't work too well! the 2.5mm SWA should be joining the 4mm swa. not comming straight from the CU

just use a 6A type B as you would on a normal lighting cuircuit

your cable rating is plenty high enough for it and its giving plenty of room for inrush currents

Why use mercury, seems a strange choice, most people prefer Metal Halide lamps for the same purpose, from what I'd heard they're becoming less popular.

Of course, who needs to bother with a lamp fitting when you can just have a microwave do the job?

Some people have way too much time on their hands, and way too many lamps and microwaves to ruin...
