When electrics go wrong!!!

@Raptor0014 Surge protected, but not Muppet protected, the fish smell is quite distinctive with out the visual aids.

You guys have seen this before, but thought it was worth posting again, the smell in the room was a very distinctive fish smell, it comes from running two 3Kw fires off the same double socket, neither the MCB or RCD reacted to the overload, just got very smelly in the room.

That’s quite concerning that neither protective measure reacted to that.

Then again if nothing created a short then it’s a failure of the socket. Especially if it was connected to a 32a MCB as 26a it would be happy with. Guessing the materials in the socket weren’t rated to withstand 26a for that long.

Is that one of the ones with lever contacts, rather than screws?

Yes, it's French Legrand socket off a 20amp MCB.

Me thinks I want to stick to crabtree...

The socket was Legrand, but the MCB and feeding RCD where both Hager and both tested out as per the specifications for them, I can only think that the fan and thermostat's for the heaters did not come on at the same time consistently, so an intermittent accumulative overload over a long period.

The back plate looks a bit corroded, maybe contacts were a bit tarnished as well?

In any case a 30% overload (26A on 20A rating) is not likely to trip a MCB but would definitely be considered unacceptable design practice. I guess the approval of double sockets was kind of based on the assumption you would not have two max loads on the same one...

 

[Mike Johnson]

The corrosion is quite normal on the ground floor of an old French farm house, no DPC or DPM so walls are always damp, if does not seem to bother the French,

Believe it or not they where not on each socket, but supplied off an extension lead onto lefthand outlet, oh can I say receptacle.

Well they can't really complain about the socket in that case being poorly made as it was clearly overloaded by 160%.

Now if only the French had a 13A fuse in the plug...

Got a call out yesterday afternoon. Told electrics had tripped, turned back on and keeps tripping every few minutes so could I come and check as had no power to sockets, kitchen and half the house.

Arrived to find the following:

Basically the far right breaker was a 50A supply to a second DB for one half of the house (big old farmhouse) which includes a 10.5kw shower, sockets, immersion and lights. Also 2 x 32a socket circuits (one of which was the kitchen) a 20a socket circuit and 16a second immersion.

All hanging off a 63a RCD and the board had never been checked in the 18yrs since it was installed.

So I managed to give them some power back. But told them they need a new board now asap and a full EICR doing, as I wouldn’t change a board without doing it anyway (especially not on house where I’ve been called to a melted board) and investigation was needed to check why that 50A breaker had obviously also overheating given the melted plastic around the busbar connection.

Received from customer:

Going to see it later today, apparently the fitting says "Made in West Germany" on it, so first question is how many others they have.
Second question is what that taped up wire is doing.

Well that kind of dates it! When did they reunify, some time around 1990?

Yeah - the wall fell in Nov 1989. It's at least had a re-wire since.

Taped wire will be the permanent live for if this was to be an emergency light. Currently (hopefully!) choc-blocked and then taped.

The Berlin Wall fell in ‘89 I think… all thanks to knight Rider himself, David Hasselhoff.

One of my regrets was not going to the Pink Floyd concert in Berlin to mark that.

There was a minibus going from Dundee arranged by Groucho's (closed now, was 2nd hand record shop and outlet for local gig tickets) but various friend could'nd be bothered and I gave up on the idea.

You'd need to go for a week just to listen to one Pink Floyd song though!!

 

[littlespark]

I remember groucho’s!

The nightlife was varied when I lived up there.
No1’s, Deacon Brodies, O’Neills… student union, of course.
Mardi gras, fat sams, de’stihls….

That all stopped when we moved to the posh end of Carnoustie
