DB2 (TT) trips DB1 TN-C-S

[GLENNSPARK]

what i wouldn`t mind knowing at this point is just who the hell told him you cant extend PME?

really iresponsible...

 

[GLENNSPARK]

Glen, steady you will be going round there, and doing it for him lol!!.

he can have guidance...but its up to him to apply it...

applying a bit of common sense wouldn`t go amis either...such as putting 2 30mA RCDs in series...

see it a lot in here dont we boys...

 

[jackhammerJIM]

lots of hear say GLENN . people are too lazy to look the information up themselves .

do you own a current regs book frenchie ?

have a look through the special locations for where PME is prohibited .

 

[cotty]

iresponsible... ?? missing something??

 

[GLENNSPARK]

iresponsible... ?? missing something??

As glenn says earth swa of shed cable at met but not at db2

Pretty sure he did not say that!

I know he didnt. I did
Meant to say no need to earth swa of cable at db2

works for high TT as well...

as in:...come down you bitch..

No! Must agree there! I'd run a separate 10mm bonding with surface trunking and a spot of 'conduit' maybe!!

 

[telectrix]

i'd use 3 core SWA. armour as cpc and 3rd core for bonding if required.

 

[Engineer54]

I'm just wondering why he ran a 3 core 10mm cable and didn't use the the third core?? So why bother running a 3 core cable in the first place??

As far as the ''You can't extend a PME earthing system'', it's mostly down to the P**s Poor college lecturers you have in these colleges and training centers these days, that continue to perpetuate this MYTH!!

 

[not clever]

Nothing wrong with what he's done (except the rcd's in series) if that's how he has designed it and is happy to waste money on 3 core but not use the 3rd core to extend the pme.
Me I'd have saved some bunce and gone 2 core swa, split the tails at the house into switch fuse out in 10mm on to outbuilding small db with rcbo's

Frenchie I'm in Andover tomorrow if you want me to sort it for you.

You can get grief from Eddy currents though!

Nope is just P**s Poor college lecturers that instead of teaching if you like, just the facts, they incorporate their own ill found misconceptions!! The same goes it seems, for RFC's now being touted as dangerous!! lol!!

i never listened to any of the old drivvel about RFCs then....and i wont now either...
and if young robert who comes out with us starts being indoctrinated by any college slavver about the `dangers` of a properly designed RFC...or how you cant extend a PME then i will be on hand to lead him back into the light...
