Irish PIRs a few queries

[Mikegh]

Hey guys

On the summary test data, the "Minimum IR" Is that a global reading they're looking for ie ; just the entire installation tested

Or is every final circuit tested during the PIR to find the lowest reading


Also for a 4(doesn't comply with current rules), how do you determine if anything needs to be done.
Do you need to know the age of the installation work ?

Same there for location of switches , are they looking for correct height from et101 on ?

Old work only needs to comply with old regs doesn't it ?

New to them cheers

Or is every final circuit tested during the PIR to find the lowest reading. each circuit needs to be a min of 1Meg. to "pass". but anything under 2 Meg. should be investigated


Also for a 4(doesn't comply with current rules), how do you determine if anything needs to be done.
Do you need to know the age of the installation work ? not absolutely necessary. but an estimate should be entered on the report

Same there for location of switches , are they looking for correct height from et101 on ? i'd imagine it's the location, e.g. kitchen/hallway/unser stairs etc.

Old work only needs to comply with old regs doesn't it ? no.it must be safe for continued use, even if not complying with current regulations. e.g. lack of RCD protection on lighting circuits does not constitute an unsatisfactory, but any present orpotential danger would, irrespective of whatever edition it was installed to.

New to them cheers

Can’t say for Irish rules, but if you do a global IR, and get a good result…. Individual circuits can’t be any less value.
One bad IR will bring down the global, then it’s a game of fault hunting

Ya that was always my thinking ,.the global IR covered most bases if it was adequate

 

[Mikegh]

And ya for the no.4 I meant complies with old rules but is safe

 

[Mikegh]

I see there ya the location doesn't mean height obviously now

like the aer fungus lingus pilot sends out a mayday with both engines dead. controller asks him for his height and location, he replies:

I'm 5'9" and sitting in the front seat.

 

[littlespark]

That should be on Uheat’s Friday joke thread as they seem to have forgotten to put one up yesterday.

Like the lady who asked the bus driver

"How long will the next bus be" ?

"The same length as this one"

That's actually based on real events

Happened a British Airways pilot over the Atlantic

It's for the installation as a whole (i.e. in parallel) or for the distribution circuit including DB with all outgoing circuits included for larger installations.

Yes they are asking for confirmation that switches etc. we're installed at the correct height and location at the time of installation.

I presume you have a QC Number?

Cheers so I think I'm right you'd be disconnecting the MPC for the global IR test at the main board, 1Mohm min is it?

The 1Mohm also applies to each final circuit as well does it not ? been a while since doing this

Personally I'd disconnect the neutral rather than main protective conductor to ensure all Earth paths are included. I.S. 10101 mentions this although ET 101 didn't.

The minimum values stated are for the entire installation/DB.

 

[Mikegh]

And what about that no.4 ? How do you resolve that issue then ?

Must be getting our wires crossed here

I'm envisaging all live wires joined at the main board meggering to the MET for the 1st global IR test

If you disconnect MPC link how are you removing earth paths ?

 

[Mikegh]

Doesn't comply with current rules I'm not clear on remedial action in all cases here

There's an asterisk on it at bottom of pir saying maybe yes/no work needed

You're potentially excluding Earth faults to the neutralising link between the ESB cut-out and the DB.

Code 4 won't require remedial action.

Sounds to me like chances of that are slim to none

Anyway cheers ,.do you happen to have a quick description for certs 1, 2, 3 is it, the difference

Also restricted and controlled works makes my head hurt

Is restricted anything that's not minor works ?

Im getting lost on controlled works cheers again
