Had to rewire some outside lights in a house. Was told that recently installed car charging point keeps tripping out an MCB. Find this absolute monstrosity.

This photo shows a garage board which is fed off the main fuse board on a 6mm twin 50A mcb. Yay. If you look at the main switch, you'll see a 16mm core on the supply side, which the car charging point firm tapped off and sent the feed to the smaller enclosure which is to the left of the picture.

Out of shot, there is a 8 way garden lighting DB, which is fed from this garage board on the 32A breaker.

Basically, all of this is powered by a 6mm cable. Which the most recent addition was a 40A supply for a car charging point. Installed when surely they knew the circuit was at its limit.

I am recently qualified and unearthed all of this. Any suggestions? Thinking a 16mm SWA from mains supply isolated, to feed these two boards?

that is a complete abortion. id rip the lot out and fit a new, bigger DB. start again from scratch.

It is rough a bit.
Do they use the charger ,or more likely ,was it a freebie?

I have seen one installed with SY , no glands on braid , and cut through straight into the side of CU . No support to charger . Lovely job.

How would you both suggest rectifying this? Builder is hassling saying he wants stuff finished today. I'm saying it's not possible. At all.

I personally don't want to touch it.

If they will not allow you the time to do anything with it then there is nothing you can do.

Tel has outlined the ideal solution, but I have the feeling it is out of your hands.
I would like to bet that this has been sprung on you at the last minute , and it has been tripping for ages . It is a typical knee jerk.

tell him that that DB does not comply , it needs ripping out before you'll put your name to the job. compare working with that to building a house on cinder block foundations instead of concrete.

Just unearthed the mains aswell. 2 sets of tails. One of them is left in a suspended ceiling taped up.

Look how they're jointed. Yay!

That lot needs ripping out and starting again with a bigger DB as Tel has suggested..........You cant polish a turd :rolleyes2:

Might have been a bit of skulduggery going on there too! be careful.

But you can. Mythbusters did it. Google "mythbusters polish a turd"

you can polish a turd, but you can't make a banana from a turd, polished or not. @OP. do it right or walk away and let some silly arse cowboy take the fall

not even if you roll one out, with a slight curve?......

have to wait till we're properly out of the eurine. then bent bananas are no longer racially persecuted.

I'm a bit confused.

Sorry, I can't see a 50A MCB. Which one is it?

Again, is there a 40A MCB, or is the charging point on the 32A?

its almost as if they have tried to use every brand of breaker possible! Gut it and put a whole new distribution setup in. Im sure it takes more effort to rough it in like that!!!
