Insulation resistance problem

Mmm, let's discuss it.

Nope. One thread is already well and truly hijacked for that purpose.

Do you say scone or scone?

Do you say scone or scone?

Scone. Notice how they are written the same though so anyone reading them should not be capable of making a mistake unless they have problems reading

Mmm, let's discuss it.

Nothing too discuss. Simple radial circuit.

I knew you would have to be different and say scone.:vanish:

Fair play to you mate, have to admit it is a little gauling that people are being fast tracked, your inexperience shows in your reason and rhyme however you have to get the experience somewhere, my advice would be to work under supervision for a while, I think people call lads in your situation 'improvers'. Don't think anyone would knock you for providing for a family just be careful out there....
as has been suggested earlier there is almost certainly a 'load'still connected to your circuit and it's not uncommon to find switches or joints hidden away in the most unlikely of places.

Good look to you and keep asking the questions, you will usually find the advice you are looking for. Stick at it and you will get there.

Do you have a alarm system connected to the RFC via a spur or a RCD FCU or socket?

Once you start to test in a methodical way as Davesparks as suggested things will become far more clear,I would definately mark the sockets once eliminated dont try and just remember them as you quickly get confused.

Lets hope you tested L/N on soft test on 250 v scale for obvious reasons.

I would suggest access to a tester which has a KOhm range as when testing on the Meg scale when it gives a 0.00 result you need to switch scale to find out exactaly what the reading is. Many MFT testers dont have a KOhm range !


If you get a very low reading then as a guide you can get a rough idea how far away the fault is using maths and cable resistance values!

Let us know how you get on lets hope its not unaccessible joint boxes!

HI, and sorry to interfere I have a new Fluke 1653B tester and I cant find the KOhms range, but I wonder. 1KOhm is 0.001 MOhm. isnt the tester accurate enough to read KOhms in MOhm range?
