Did EICR today...

[Eddiesparks]

...no supp bonding or rcd on lighting circuits in bathrooms. C2 i said. According to esc pdf guide!! Easy fix, spare three ways in 16th ed hager board. Busbar is long enough. Install rcd.

Wondering if i can get any hager one to replace pictured are sizes universal?

I thought save money and get 63a one and mix and match lights and sockets so not all of one on one side etc. 100a a bit generous no??!! Wylex provide 63a seemingly as standard.

Thanks boys and girls

 

[Sintra]

The 100A or 63A rating on an RCD is just the maximum current that can safely be put through the device. It does not provide overcurrent protection. Therefore installing a new 100A 30mA RCD would be fine.

 

[Eddiesparks]

I know that mate, 100a one is much dearer so was asking can i get 63a (pr thereabouts) one to save money.

Basically, ignore everything else;
ARE HAGER RCDs UNIVERSAL IN PHYSICAL (not CCC or breaking cap.) SIZE?!?!

Fanks!!

Yes they are Hagar boast that they do not alter sizes etc. when bringing out new ranges.

 

[Eddiesparks]

Wicked thanks a lot.

 

[micknew]

Glad to help mate.
Apparently Hagar are the only manufacturer that maintain specs. so that new breakers can be installed in old boards.
Wish others like Wylex did the same!

 

[GLENNSPARK]

this is all about Max. demand.
stick with the 63A..it will be fine..

 

[Eddiesparks]

Tbh if they did a 30a one would prob be fine too but i'm just playing devil's advocate!!

How would they make a fortune making us change boards if everything matched there is method in their madness

Consideration should be given to the primary overcurrent device.
IE is it a 100a cut out fuse, needing 100a capable equipment?

so is the RCD in question operating as the main incomer?

 

[Eddiesparks]

Nope, 100a main dp switch first.

 

[KAS1]

Why was this coded a C2 and not a C3 ????? or even no code ??????

 

[GLENNSPARK]

Nope, 100a main dp switch first.

and you have some unprotected ways served from the incomer....so think parrallel paths and what happens to current & voltage...
63A will be fine...

 

[dave274]

Its c2 because theres no supplimentry bonding and no rcd, an rcd is one of the requirment that must be met in order to omit supplimentry bonding.

 

[KAS1]

Did you test to see if supplementary bonding was required, at the most no RCD would only be a C3 wouldn't it, as it may not pose a danger even under fault conditions if all other conditions for disconnection times are met !!!! to just slap a C2 regardless doesn't seen right IMO

 

[Rampantchilli]

If you have supp bonding but no RCD the ESC guide states C3 however if no supp and no Rcd the its C2. IMO I'd C2 that without testing if supp was necessary,

 

[KAS1]

Why !!!!!!!!!!!!!!!!!!!!!!

 

[Rampantchilli]

Why not, from advice I've been given by NIC, ESC and other electricians, this would be tested against 17th, whilst ok at time of install(perhaps), it doesn't not comply with current regs, therefore requires some code

 

[Flanders]

why not just fit an RCBO for that circuit

 

[Rampantchilli]

why not just fit an RCBO for that circuit

Because he was doing an EICR

 

[Flanders]

I Know that but I thought he was looking for a solution to the observation he had made so he could quote to do the remedial work . Just thought it might of been cheaper and easier to do

 

[brightspark2010]

it does say lighting circuits in bathrooms plural 2x rcbos more money

 

[Guitarist]

I would have suggested RCBO's as well.

 

[GLENNSPARK]

Why !!!!!!!!!!!!!!!!!!!!!!

actually theres boxes to tick on an ECR for this...
no RCD but supplementary bonding is present & connections have been verified then no RCD would just be noted...
no RCD and no bonding is a 2...

 

[Eddiesparks]

I fitted rcd in the end but it was a pain. Should've fitted 2 rcbos to upstairs and downstairs lighting circuit and had done with it!

Hate to say that we told you so....
Oh dear, I just did

Mind you if you look on the bright side you have now made the installation fully compliant with the 17th addition which can't be a bad thing

Agree, just so long as he managed to mix and match as he planned
