yep the prat had picked a red and a black,only prob was it was a live and switch wire!

worked for a company doing lofts and went to a job where one of the lads(not a spark) had wired the loft light into a jb and when he switched it on the florry strobed, he also found the bathroom light glowed dimly but when you turned bathroom light on loft light went out, he was convinced wrongly that it was a fault with existing wiring,.took me about 2 mins to work out what he had done.answers on a postcard please lol.

It is 'nice' when you (easily) sort someting like that out and can smuggly call 'the lad' a right muppet!

went to give a quote for a 3 bedroom rewire. turned out that its a 3 bedroom, with extension at the back and a newly built loft extension. customer wanted to have 3 power showers installed there. 2 were already in, ending in a fuseboard with 10mm tails. one plugged together with a ring circuit. customer wanted some parts of the install be left alone, all work to be done in 4 days, and lots of haggling over the price. I walked off at the end.

Hi. Am after some advice if possible please.

Have moved into an old victorian house and am currently refurbishing it bit by bit. Have included some photo's of what the CU and main fuse are like at the moment. Not a pretty site!! The CU is halfway up the wall but the RCD for it is under the stairs fed by a 10mm cable from the cupboard which is 6 feet away on the other side of the wall. God knows why it is like this!

Am looking at upgrading the electrics to a new split board but just wondering what the best way to go about it would be? I am currently taking a testing and inspection course so that i can sign off my own work but would like any advice if possible.

Thanks

As far as the replacement CU is concerned save both your money and time buying a complete CU, just remove the existing MCB's and go all RCBO!! This is a far,far better option than any other RCD configuration CU!!! These dual RCD CU's can be nothing but a heap of trouble when a fault occurs...

I have recently rewired a four bedroom house for a friends parents. One the first inspection visit, I went into the attic, "Throw down the cable with the plug on it" I was asked. I passed it down, stupidly now I know. He proceeded to plug it into a socket outlet on the landing. Swiched on, and hey presto we have lights in the attic.......... After no more than 20 seconds, I shouted "Switch the socket off" I came down, unplugged it and told him never to plug that in again. "why" he asked, "We've always used that for the lights up there". I proceeded to open the plug firstly, 13 amp fuse....... secondly, other end of the flex, another plug containing 13 amp fuse. This plug was plugged into a socket screwed upside down on a roof truss. And to top it all off, this provided the power to two 100watt bulbs in the attic. But the cable running to these lights was speaker wire. It was still hot when I had removed it and showed him......"Thats all I had and its worked fine for years" he said. "I think you have just been very lucky I replied" The jobs finished now and everythings safe and up to regs. He now is the proud owner of a totally rewired house and two energy saving lights in the attic running of the upstairs lighting circuit and operated by a pull cord switch which you operate when the hatch is open. The earth wire attached to the TNS supply was only 4mm and there was no other earthing accept for the cpcs in the cable. I have found that many people think/assume that if the electric works and the telly switches on ok, everythings ok. Especially the older generation.

I’d get the gravity checked out first, there seems to be a temporal anomaly.

As E54 says fit RCBO’s, do some tidying up and all should be good. Eeerr correction a lot of tidying up. I’ve corrected the anomaly before I put my neck out. where’s the T+E go that’s in the Henley?
I wouldn’t sling that board out if you can get RCBO’s for it.

 

[HandySparks]

What's the means of earthing? Looks like it might be a TN-S system, but not an arrangement that I've seen before. Have you measured the Ze? (Maybe not if you're still doing the course.)

If you go for RCBOs (which, I agree, would be good), whether you keep the existing CU or not isn't much of a consideration. A new enclosure with main switch will be about the price of one RCBO, although there'll be the time taken to do the swap.

Where are you located? England or Wales, or elsewhere? ie does Part-P apply where you are?

 

[leejcooper]

Thanks for all your replies

Sorry photo's upside down!!!

have already brought the CU when i moved in too long ago to take back. Was looking at moving the CU next to the meter as need to box in the wall where it currently sits.
No have not carried out any testing yet but am expecting problems when i do.
Am located in England so come under Part P
The T+E goes to the RCD under the stairs in the hall, forgot the photo, which then supplies the CU so meggar mess.

Got called out to a job, lights flickering like something out of a film...

Problem ... Gardner had gone hit the incomer with a spade and never told a sole

 

[sedgy34]

had rcd tripping the socket box was earthed and the wall was damp

Finally got round to lifting the landing carpet in our new house to paint the skirts and fix the ever present squeaky floorboard when this caught my eye:



0.5mm stranded flex wrapped around the central heating pipes. It's part of the downstairs light loop above the kitchen which has been modified somewhat then just taped up and left. Needless to say it is much safer now.

Gives me an excuse to the the bedroom floor now and have a look, might as well fit some downlighters in the kitchen whilst I'm there as 'I don't know what the rest of the circuit is like dear wife!!!'. I knew I could get rid of the crappy mini GU10 light bar we have...

Nice! Glad to see you practice safe isolation in picture two
