What a mess!!!!!!!!!!!

[Steve T]

Hi

Today I found a horrible mess of wiring for the heating/hot water under the box my megaflo is on. Here are some pictures.

My question is should I sort it out or leave it? Obviously it does work, but it is messy and a few cables have scorch marks from touching the hot pipes.
If I go ahead and sort it out, I'll probably put it outside the box the megaflo is on, but this would mean extending the three 3core+e cables.
What is the best way to extend these cables?
The flex cables would not need extending.

Thanks in advance for any replies!

if it's only been fitted a few months ago, complain and get the cowboys back to do a decent job.

The plumbers who did the boiler change did not do any of the electrics shown in the picture, they were done about 10 years ago when the house was built. But they put in the filter. I did get a gas safe certificate from the install.

Whilst the current set up isn't 100 % desirable what is actually likely to go wrong.... So you could leave it

I would use regular junction boxes to extend any cables that need to be extended and take them all into an adaptable box of some sort. 2-3 flex glands in the side of the box will get all the cables inside nicely and then use some connectors/wagos/din rail connectors to terminate everything.
No need to extend them using IP rated boxes.. you could go on for ever saying 'what if the cylinder leaks'.

I think members are saying IP boxes not for this reason but they can be drilled and compression glands can be fitted regular junction boxes are ok but the cable going into it would need to be secured.

if not disturbed not a lot however if it is regular use i.e. airing cupboard terminations could be vibrated loose.

Hum ..... Exactly, or a water leak possibly.

well if you want to assume the worst but should not happen and you could apply that argument to all the plumbing in the house.

^^ precisely.

The choice is leave as it currently is, or add loads of extra connections that could fail ..........

If installed with good workmanship why should the connections fail ?

Thanks for all the replies and advice, I'll go ahead and change it as it's really messy, and also I have had a look at the terminations inside, and a lot of them don't look very good!

"IF" ....

Any and every joint is a potential point of failure, regardless of how well made it is it will never be an unbroken conductor.
This holds true for anything, whether it is electrical, mechanical, structural etc etc.

or could just wrap the box up in 2 layers of metallic duct tape. if there's a poor connection inside, this will keep water out and stop the electricity escaping.

It's not good having a big connection box like that with no strain relief on the cables. Once someone moves it out of the way to clean the Magna flow there's a lot of strain on the connections inside, especially with most of them being solid core cable.
It should be either fixed to the wall and the cables clipped (probably not enough room), or replaced with something with strain relief for the cables.
As above, no point going to the extremes of making it IP rated.

Can't you just leave it where it is and tidy it up? Or maybe locate it in a position where cable extension is not required?
I'm not a personal fan of extending cables unless its absolutely necessary.

Yes agreed it isn't great. But what poses more of a risk. Leaving it as it is or an unqualified person without sufficient knowledge relocating it?? I know which I believe poses more of a risk.

No one seems to have mentioned these yet: Honeywell Junction Box - http://www.NoLinkingToThis/p/honeywell-junction-box/66443

Am I missing something?

If you had the boiler installed a few months ago, call the plumber back to sort out the mess he left behind, he must have gone in the wiring centre when installing your new boiler. If he refuses or claims it is ok, you are within your rights to get gas safe out who will do a free inspection of the work and they will make a friendly call to the plumber to pop back and tidy it up.
