Rcd protection

[lkayelectrical]

I know when we modify ccts we are supposed to bring it up to regs ie rcd protection

I've all ways done it back at the board ie if we need to add a new socket can we just put a rcd spur from the old socket but before they new one? Or do we need to protect the complete circuit?

RCD spur is fine, have no idea what the reg number is in the BGB (really must read it this weekend)

Can you not add an RCBO to the board?

 

[lkayelectrical]

No unable to do rcbo as it's a old school cu, there is a socket I can spur off for the shower supply but was wondering it rcd has to be done at source of if I can go from the socket to a rcd spur then up to shower, as all ways done it at the board.

You only have to add an RCD to new work if I remember correctly.

[Andy™]

only your work needs RCD'd. so RCD spur would do. do whatever is easier

 

[Taffny]

If it is just one socket why not use a socket in with an inbuilt RCD.

the cable feeding it may need RCD'd

Mmm am I reading this right ??

 

[Taffny]

Agreed, it would depend on the cable or how it was run run. Should have worded the statement differently.

What type of shower are you supplying from a spur off a socket ?!

 

[Robin Spark]

We are hoping a pumped shower supplied with hot water But I am sure the OP knows this and has been given the correct information from his client.

What type of shower are you supplying from a spur off a socket ?!

8.5kW of a single socket....

or use a double with parallel plugs if its a 9.5kW or higher ?????

:innocent

Mmmm...

dunno:C

think you may be holding the screen upside down maybe??

Surely a shower pump on a plug top is classed as a portable appliance and not part of the fixed installation. Would put it on an rcd spur for any extension to the circuit or rcd SSO if just plugging in and no rcd at origin on cct.

I guess he's got to extend the fixed installation bit so he can plug his pump in without having a bit a flex trailing out across the landing.?

May be wrong tho?

I've a quick question about shower booster pumps..

Do the manufacturers instructions state that they need to have RCD protection?

Even if they didn't the fact its a shower, its now a special location so needs Rcd protection.

Back to the OP, if its an old school board how are you providing Rcd protection for the lighting circuit & any other items within the room

Edit, i suppose it could be a pump in a cupboard or under a bath, i was thinking of a wall mounted unit. The last pump like that i fitted had no mention of an Rcd

 

[lkayelectrical]

I'm not modifying the lighting cct, any way lighting ccts are easy to resolve rcd spur next to board but 30a on a 13 spur isn't so easy

Shower just one of those digital ones needs a spur in the loft only 3a or so. He doesn't want to get te board changed yet as is having a large extension next year But currently only has one of those carp bath mixer showers

As you eventually guessed, the pump is not in the bathroom (it's in the loft) and is connected to the pipework by plastic push fit flexible hoses. Only asked because I have a job to price and the installation is currently on Wylex standard boards with 3036 fuses I did say to them that they should consider an upgrade at some point, but they do not want it doing now

 

[Andy™]

depends on manufacturer - some might say it needs RCD, other may not

so if necessary you could use an RCD spur, or even fit the pump with an RCD plug instead

 

[SLIPSHOD & SLAPDASH]

In this case no work is being carried out in the bathroom, the reason i mentioned the light was if you were adding an electrical circuit for the pump in the room then the bonding/rcd to all circuits in that room need to meet current regs.
