Resistance bewteen circuits

[Jimmyb]

I just wondered why i would get a reading of 1400 - 1800ohms between lives on 2 different circuits one being a new circuit installed about a month ago by an other spark, the only reason i check was two ring mains that had been put into one mcb by the last sparks and told the customer he need a new board fitting to allow for the extra circuit and he would come back but then never answered the phone since, hence i got the job of changing the board.

I cant remember ever testing between to live on circuit and wondered if i was missing something and there is a normal reason for this. I did check all over circuit and all >2000.

Many Thanks

Jimmy

You need to do full continuity tests on both RFCs, paying particular attention to polarity at each accessory, I think you find at least one accessory is reverse polarity L-N or L-E. Also somewhere on the RFCs you have an approximate 40W of load (lamp, fan, etc.) still connected in circuit.
