Triton shower rcd issues

[sc_7901]

hi there, I’m just looking for opinions/advice. A couple of years ago I had a 8.5kw Triton shower installed by a local company. In May it broke. Triton installed a 9.5kw omnicare. It’s broken again. Triton say the rcd is the issue this time. The RCD is 40 amp which apparently is not strong enough. What I find astounding is Triton did not check the rcd before installing the new unit. Apparently it’s not their job! Apparently the rcd wasn’t even right for the old 8.5kw shower either. Am I wrong for thinking Triton should’ve checked the electrics before installing the new one? I know they couldn’t have fixed it but I’d rather they had done that than leave me with a broken shower after 2 months!

they are talking out their corporate arses. 9.5kW = 40A, so the 40A RCD , although on it's limit, will not cause your problem.

And how would an RCD break a shower?

 

[sc_7901]

My other half has informed me although the rcd is 40 the circuit breaker is 32. Would that be the issue?

 

[sc_7901]

Strima, seems like the shower is tripping the electrics. Triton are blaming the rcd

 

[telectrix]

a 32A breaker will trip at 40A in approx 10 minutes. that may be your cause.

What is tripping?
The mcb?
The RCD?

Yeah, the shower will work for a short time and then cut off. Is it correct that they weren’t even suitable for the old 8.5kw shower?

The RCD

What is good practice? Should Triton at least have had a look before installing the 9.5kw unit? Seems crazy that they wouldn’t, regardless of the fact they couldn’t rectify it.

If the rcd is tripping best you get the circuit and the shower tested .... .

Probably cost you about £50

Then you will know where the problem is

 

[Strima]

Did they carry out any form of testing when they swapped your shower and more importantly did they leave any certification?

TBH I know the answer already...

As far as I could tell, the only testing was switching it on. I wasn’t given any paperwork

Would the original installers, the local company who installed the 8.5kw, be liable since apparently they’ve installed the wrong rcd to begin with?

The RCD

Not taking the rise Mate, what else doesn't work when the Shower trips? is your fuseboard a modern one with 2 RCDs or just 1?

 

[sc_7901]

It’s just the shower that goes. That’s about as much as I can tell you. Sorry. Am clueless about this stuff. Looks as though the board was put in in 2010

Without being there it's difficult to address the problem, but usually the RCD will be connected in conjunction with a number of MCBs, but you say it's only the shower that doesn't work, this makes me think it's the MCB that is tripping not the RCD, can you post what is written on the device that trips? Or better still a picture of the Consumers Unit (fuseboard) showing the item that trips.

 

[sc_7901]

Hope these help!? On the bottom picture, “shower” is to the left of “lights”

 

[Pete999]

Looks like a standalone RCD feeding the shower, can#t see how it will be a load issue, more likely a fault in the shower wiring or the shower, you will nee to get the wiring and shower tested by a skilled electrician, with the correct test gear.

Thanks. The guy from Triton is insisting no issues with the shower cos the guy checked the wiring. Sparky it is then!
