Testing installation after cu swop.

[mikeymoo]

While testing an installation after a c u swop, do i need to test and mark down results for an overrun fan in a bathroom and toilet separately from the light circuits? Both are supplied from the lighting cct...

Are these the furthest point on the circuit?

The bathroom is on the top floor. But the toilet on the first floor isnt.

MIKEYMOO!

A little bit of advice... ALWAYS test the wiring BEFORE you do a CU swop! This way, if any remedial works are needed you can bring such to your csutomers attention PRIOR to changing the CU which is the stage where YOU become responsible for the job.

I've had my fingers burnt in the past and locating the reason why there was no ring continiuty was more than a loose connection within a socket backbox.

BY THE WAY EVERYBODY - I need new work prior to becomining yet another statistic of the credit crunch - any time any where but not any one... . What I do can be seen on Intro

Record the highest R1+R2 & Zs measurements for the circuit...

sound advice. Test the circuit you are modifying before you work on it. Other wise you may open a huge can of worms. I recently carried out work on a house only to discover during testing that the earthing was inadequate (37 ohms! as opposed to 0.3). Which was clearly dangerous as there was no RCD installed either. I was unable to determine the type of earthing arrangements due to the main earth disappearing into the ground about two metres away from the main supply.
But the answer is always test the end of the circuit or the next nearest available test point for that circuit.

Thanks for advice..
