rcd meter tails

[deanmac]

hi i tested a domestic property earlier,and someone has sunk the meter tails,the fb is a 17th edition,my question what size external rcd is required for the meter tails,its a pme system,many thanks

"sunk the meter tails"????? more info. needed.

if you mean that the tails are buried in plaster < 50mm deep, you need a 30mA RCD. that buggers you up as regards discrimination.

Chased into the wall I suppose

 

[deanmac]

yes they are buried in to the wall

dig them out and put in trunking.

fast fingers.....
but it took you hours to get round that show.....

had to kill time till beer o'clock.

 

[deanmac]

its not an option,they don't want the wall disturbed,so does it have to be a time delayed rcd

disconnect the old ones....replace with new...
come on lad...its that simple...

a time delay would not comply. you say you.ve tested the installation. code C3 ( 522.6.101 ) END OF.

i have those options to the customer,they want nothing surface in trunking etc,they want the rcd optionso does the rcd have to be time delayed ?

 

[deanmac]

so a 30 mill would suffice,thanks

theres no mechanical protection to them buried tails.....
so where you getting time delayed from?....
look, you have obviously made your mind up so you go do what you want....

They are askjing you to do something contrary to the regs. So it's a no-go. To comply with 522.6.101, you would need to fit a 30ma non-delay rcd. This would mean you'd have 2 similar rcds in series. Basically you're snookered.
