New Electrician asking for help with a shower please? :)

[Catch22]

Hi guys and gals,

I recently went to a customer's home and disconnected a shower ready for a plumber to come and install a new shower cubicle and re-connect the pipes for the shower. When I came back I found the cbale was now to shoort so had to include a new piece of cable to reach the shower. As it was an older installation I decided to add in a DP isolator pull cord, means of isolation etc and so forth. A few weeks later the customer is coming back saying that the shower is cutting out at the MCB after a few minutes of use.

The shower is the same as is the cable run to the isolator. All that's new is the cable from the isolator to the shower. I can't figure as to why it would now do this considering it's the same shower and power supply?

I have yet to inspect the shower again, but didn't want to go in looking like a complete idiot as I'm sure you can all understand so wanted to try and get some advice prior to getting there.

Many thanks in advance!

Dan

This is a joke right? Are you a plumber?

 

[Catch22]

2330 lvl 3, 17th, part p. No I'm not a plumber. Sorry I clearly didn't have the same apprenticeship as you.

So what bonding is in place?

 

[2na]

No you definitely don't if you list part p as a qualification.

 

[matdom]

If you're registered on a part P scheme, I would suggest not using this job as part of your assessment!

If he is registered, he still has another year before he has to do a job properly again.

 

[Catch22]

Main bonding is. 2na please stop, you're not helping you're just trying to instigate something. Please I'm after constructive help.

I'd guess that the new shower and old shower are the same make but different KW rating.
Plumbers mistake possibly.

 

[Plonker 3]

What about Supplementary bonding?

 

[SJD]

I'd guess that the new shower and old shower are the same make but different KW rating.
Plumbers mistake possibly.

Some showers come in several ratings, e.g. 8.5, 9.5 and 10.5 kW, though it ought to be obvious when buying it, as the prices will vary (quite apart from being marked on the box). Unless someone was asked to buy one and not told the old rating. Or perhaps thought it would be nice to have a bit more power and not think it mattered at all.

 

[2na]

Size of shower.
size of breaker.
insulation resistance readings.
r1+r2.
earth loop.
loose connections.

all you need to find a fault.

 

[Catch22]

No supplementary bonding.

 

[2na]

If you don't have it by step 3, surrender.

 

[Plonker 3]

No supplementary bonding.

You claim to have the 17th edition, oh dear.

I would take the banter as advice if I were you...
why did you carry out job if the customer didn't want it doing right?
Would love to see the part P submission form for that job!
