insulation resistance

[Buzz-light-bulb]

I'm fed up of having to disconnect all conductors out of the rcbo's to obtain an insulation resistance test, does anyone having a better solution to bypass this to make life easier.

hmm..

so theres some in here whingin..caus the prods cant get into the RCBO...

so i suppose it never dawned on them to get a couple of screws to reach in...get the crocs on the screws...and thus through them onto the terminals..


god...sometimes...:nonod:

Well since you've gone and given the answer away,
I use a normal screwdriver with the croc clip attached to it, you can hold the handle and apply proper contact pressure.

A normal screwdriver?...........(faints)

 

[Richard Burns]

or even a croc clip on a short length of a core of cable that you may have to hand?

 

[davesparks]

Can't get good contact pressure that way though, a screwdriver you can push with the handle, bearing in mind you also want to get in there for your RCD test.

How about doing the IR test before you connect them to the RCBO in the first place?

What about periodic I have raised this issue before, MEM are an absolute nightmare have to remove L a N arghhhhhhh especially when you have a limited time to test a monster TPaN board full of the *******s

What if I use an off cut 2.5mm conductor linking it to L - N terminals connected to croc clip and other croc clip to earth bar, or would i get a false reading due to the rcbo

Read 612.3 'i' of the regs 'pre test checks'.

 

[HandySparks]

Read 612.3 'i' of the regs 'pre test checks'.

In which edition of the regs?

 

[se7aq]

the green book

 

[se7aq]

Read 612.3 'i' of the regs 'pre test checks'.

Ooops, Sorry. Read 10.3.3 Pre test checks 'i' in the green on site guide

 

[trev]

Why are you on about pre test checks when the op is asking about the test?

Depends on the make but 9 out of 10 probably yes you will get false reading

I hate doing periodics on a board full of RCBO'S bloody nightmare in fact installing a new cu board full of rcbos is a pain to get it neat and tidy as there is never enough room. give me a split board any day for ease of future maintenance and testing.

I understand the discrimination offered by rcbo's but you can always turn each circuit off to see which one trips the rcd.

rant over lol
