Does anyone have a quicker or safer way to eliminate the problems caused by neon switched sockets or dual pole switches etc, while running the schedule of tests on a ring or radial circuit. I would think the best way to eliminate the effects caused by the neons on the test results is to disconnect the fitting with the neon completely and replace it with chock block for the dutration of the tests, or is there a better way?..

The neon should only affect the insulation test, and then only that test between line and neutral. If you carry out tests on line to Earth and neutral to Earth you are "testing" all conductors - just note on cert that line to neutral not carried out due to neons on the circuit (ass covered).

Removing the neons is nearly impossible without damageing the accessorary, removing accessory and replacing with choc block may be an option if there is only on or two outlets - any more than that and you will be wasting quite a chunk of your valuable time.

Thanks Dinosaur.. that helps.. Its quicker than disconecting them and having to backtrack reconnecting them after the testing.

Make sure the switch on sockets are in the OFF position and not in the ON position when you do your testing. Neon should only light when socket has been switched on.

Ahh . Neon locator plates, MK used to make 'em (and probably still do). Yes , wired across the switch, light up in 'off' position, and go out in 'on' position.

Hav'nt heard of them in years !

Hi Wayne (Wasn't that a picture by Constable?)

You must deal with the same sort of people I have dealt with.

Asked to do an inspection on a house, as part of survey for a purchaser, and the vendor had fitted plastic plates under all the swiches which illuminated. Apparently you could by these from the"sheds" at one time.

Happily spent ages disconnecting them all then reconnecting them once I had worked out what was causing the wierd readings I was getting.

Then there is the person who changes their 20amp isolators themselves and reverses the feed with the load.

It's a great life though isn't it?
