started a job before the 17th came out etc

[sparkyork]

hey all ive got this job that was started before the 17th came out, installed some downlights (1st fix) and the customer has just got back from a long break, can i still fit these downlighs (2nd fix) to the 16th??

 

[montybaber]

Im pretty sure thats fine, circuit designed before 17th

 

[simonatlondon]

thumbs up from here too!

 

[sparkyork]

good good we are goo gooo goooo all clear for take off roger!

 

[Cirrus]

yup yup - 16th is fine!

 

[Shakey]

crack on Rich, just make sure you sign them on 16th edition certs

 

[sparkyork]

yeah lol! i tried convincing em to have a board fitted a again its one of these old earth leakage devices protecting the main switch on a tt system.

do i need to make a not of this or just fit me lights as normal and forget about this??

all main bonding is "a" ok too

depends, if its a current operated ELCB, the nideally it would be changed

However its a VOELCB (voltage operated), as far as i aware it HAS to come out.

Either way, they are often as high as 500mA, so will not provide any appreciable shock protection

 

[sparkyork]

how can i find out this info as there's never that much written on them??

and what would i put in? a 100ma device? and is this inline with 16th regs!!

 

[EasyFox]

Look in the back end of the part P document, there is info there on VOELCB's

But if the unit has 2x links to earth (1 at top & 1 at bottom) odds on it'll be a VOELCB, they are to be binned/replaced because parralell paths to earth renders them inoperative. They were banned because of the advent of sup & equi bonding back in the early 80's so I was told.

 

[sparkyork]

cheers easy will check it out, you mean approved document P?

what are the ones that have both earth connection at the bottom are they the other variant?

and whats best to replace them with, a double pole rccb or ??

Whats the earthing system ....TT?
Is the cu the old 3036 type?

If so 100m stype rcd to replace the voelcb & slap a remote 30mA rcd(s) to cover socket circuits.

 

[sparkyork]

yeah its a tt and 3871's, 10mm main earth bonding.

so just to clarify then its good practice to get shut of these devices in favour of better ones, so is this as impoartant as say checking the main bonding as well?

the works are to the 16th so do i still need to upgrade to 30ma? i must admit it gets a bit confusing, all i was doing was some downlights and ive not gotta upgrade the protection on the socket circuits??

im all for safety but where do you draw the line on things? in this situation!?

 

[EasyFox]

Sorry I got carried away & forgot it was the lights you were working on.

Just put in the 100mA rcd (personally I'd go s type but thats upto you), then note on cert no 30mA on sockets, might be advisable to put a recommendation letter advising lack of 30 mA rcd is a bad thing in with the cert to the customer.

so just to clarify then its good practice to get shut of these devices in favour of better ones, so is this as impoartant as say checking the main bonding as well?

yep, because they will not operate as intended due to paralell earths via bonding.

 

[sparkyork]

cheers easy feel a bit better now! ill get hold of a 100ma s type (time delay?)
and like you say will add note and do a letter aswell.

its a whole new ball game been self employed! before it was someone telling me get rid of this and do that!

never seem to get chance to relax, i guess its only early days but its just work work work!!
