Strip lights went off, trip switch turned back on, lights still won't come on

[dannyboy]

Hi all, 1/3 of my lights have gone off in my shop. The rest are still on. The trip switch was turned off, but when I turn it on again the lights still won't come on.

I've tried replacing the strip light and starter in case they were blown but they still won't come on.

I'm no electrician so haven't a clue but i'm guessing its a fuse for that particular circuit for those lights? Do I need to remove the cover off the trip switch box?

Yes, should be individual fuses for the lights, sockets etc, etc. cover on the condumer unit usually flips down to reveal the fuses.

Cheers mate, I had a look but it needs to be screwed off, just didn't wanna mess with it in case I was looking at the wrong thing

Normally don't need to be screwed off with a screwdriver. Maybe one small thumbscrew to unscrew on the older boxes. Post a photo of the fusebox. (">

Here's a pic of the trip switch box, was the 3rd switch from the end that tripped off

U need to check the voltage in the fittings that don't work. Are all the lights in the shop of 1 switch?

There are no fuses. You don't need to remove the cover. If you've replaced the fitting and they aren't coming on, something more difficult to diagnose is the fault. Do you have a multi-meter?

[dannyboy]

Scooby, no the lights are over 4 switches (2 x double switches). No Geko, no multi-meter

check switches, one might be faulty,also lighs might be fed of a hidden fused spur unit.

from your photo im trying to see whats written under the red lights,looks like socket,so maybe lights plugged into a socket somewhere.only guessing,if i stayed a bit closer would come round f.o.c.

I think you need someone to check it out. You don't seem to know what you are looking for, or how to identify it.

Would someone run a mains ring on a 6a fuse?

[dannyboy]

Thanks guys, I do have a customer come in every few days who's an electrician so I'll get him to have a look. I've been in the shop 5 years now though and never had this problem.

I'll get him to have a look anyway

Nothing would surprise me.

I know a qualified electrician that run an 8kw shower from a 15 amp fuse. He almost burnt the house down. He didn't want to take any chances with a shower (electricity & water and him standing in it), so he fitted a 15 amp fuse when he installed his shower unit. He probably didn't have the shower on full flow so the shower heater element was cycling on and off so the fuse wire was glowing almost red hot but not quite blowing before cooling down again. The bakelite fuse holder however was storing this heat and getting hotter and hotter until the fuse box caught fire.

He came in to work on the Monday morning and told me he almost had a fire under the stairs. He told me the fuse box was burnt and charred next to the shower fuse. He then said "I don't know how this has happened. All connections were tight and I fitted a 15 amp fuse just to be on the safe side". I had a pretty clear idea what must have happened but when I tried to explain the above to him he just couldn't see it. (">
