What in a house should or could be connected across L-E ?, having issues

The last three CU changes I've been to I have picked up L-E and N-E readings of 0.01-0.03 Meg on the pre tests before I quote, there is not enought fault current to blow the 3036's in all three scenarios but enough to trip a 60898, I cant remember this happening before, unless I'm having a moment can anyone suggest what would be directly or normally connected accross L-E?, ive found surge protection protection devices hard wired in the past that cause this but cant think otherwise

cheers

tv boosters, faulty extension sockets...

Back boxes full of damp plaster or tile adhesive. The 75mm-long accessory screws give the game away.

Is the property TNC-S?? as this can often explain any N-E anomalies

Neons at switches.

but enough to trip a 60898

23mA won't operate a BS EN 60898 circuit breaker of any description.

rcd spurs or surge protectors

A fault!!!!:earmuffs:

I take it this is a globle test pre CU change.

Once you start testing the individual ccts you will have more idea what/where the faults are!

Good luck!!

Whatever the fault current is 23mA maybe I can assure you it trips the MCB, Fair do's Lenny I must be on an unlucky streak 3 in a row
