Changing an electric shower 8.5kw to 8.5kw

[LadyM]

Hi our triton Jade 2 eletric shower has finally bitten the dust and we are looking to replace it with the Jade 3 as the connections are all in the same place so hopefully it should be fairly straightforward as we are looking to do it ourselves. I just have a few questions I want to check.

The cable looks to be 10mm and it is on it's own separate circuit, there is a 30amp rcd on it too so I presume the electrics are ok as I am not upgrading the power of the shower!

The existing shower is connected to the cold water main by a compression elbow joint, I presume I can use this again and just use a new olive, the inlet on the shower is plastic is that ok to use an olive on?

I have read that the cold water pipe needs to be flushed to remove swarf, is this still the case if it is an existing pipe or only for new ones?

Is there anything else I need to take into consideration?

Many thanks

As you correctly say, the electric cable doesn't require upgrading, and by all means use the same compression coupling (with a new olive) if thats whats required by the manufacturers instructions.
As the pipe work hasn't been altered, there shouldn't be any new debris in there - but there's often an in line filter to check on this.
Its probably best to allow a qualified person to reconnect the shower electrically, as you are dealing with heavy current loads. In particular, the earthing requirements are crucial.

I changed my own Mira shower a few months back. The connections were straight forward, relatively easy job, but just make sure when you fit the compression elbow onto the plastic pipe, push it all the way in. Sometimes you need to give it a bit of a strong push to get it fully in all the way.

They do recommend a qualified electrician fit it, but as long as you follow the manufacturers instructions exactly as they are, you should be ok to swap this over. Make sure you turn of the electrics first though.

I'd agree with this.

a 30a rcd wasn't big enough for the old one & it still isn't big enough for the new one

shame on some of you for missing that

I was assuming the OP meant 30mA RCD which is fine. Are you confusing RCDs with MCBs? All the more reason to have an electrician check it over.

If the OP needs to ask these questions I'm not sure they would know the difference between 6mm & 10mm cable,

They said 30amp rcd which i'm guessing is what is written on it & if it is then it's not big enough

get a plumbtrician to do it.

 

[denso13]

i'm guessing

if a customer tells me it says 30amp then that's the rating, why on earth would someone look or even know what mA's it trips at, it seems to be you that hasn't got a clue & has been giving the OP some wrong info
