Ring main no continuity on live ends

[Mikey10695]

Hi, Im a bit puzzled, recently did a new kitchen install with complete new wiring from the cu, this included a kitchen ring, upon testing I have continuity on the n to n end amd cpc to cpc but no continuity on the live ends, Insulation resistance checks out fine on investigation using the half test method, so im confused to as why this is?

Kev has drilled through your cable somewhere ?
Just check line continuity socket to socket to find the break.

Spilt ring set up r1+r2 as if it's a radial. Test at each socket when you loose r1+r2 continuity your issues is between that outlet and last. But you do have to figure out the correct socket order.

Due to the run of the cable from the cu to the kitchen is restricts me from the r2 method so I was thinking if I connect the line to earth at the db of leg 1 at the board and then use my multifucntion tester with the plug attachment at each socket this should narrow the problem down?

Yeah, that's what I meant. This is the R2 adaptor, it'll save you taking off the sockets:

He won’t spot the reason for the fault if he doesn’t take the sockets off!

You know what I mean!

I will second Timbo's response.Kev the kitchen fitter has drilled through the live only of one of your cables.

No I totally agree mate, during my apprenticeship I never really came across any fault finding so I have a little experience, also in college we never really went into depth on it so Its the things like this they need to teach more at college, I know you get more from the actual on site experience but if you dont come across it then its not something you will know but I get what youre saying.

Well you've come across it now.... and it's called on site experience
