Odd goings on.

Ive just had a pro electrician in to hook up my extention (2 rooms, 3 spurs: sockets/ downlights/ smoke alarms) wiring into an RCBO unit > into my mains. All tested & docs sent to Buildsing Control. The wiring, sockets, lights etc done by a competent other, the pro happy with work.

 

1st thing I plug in, a drill to do make my steps/ finish off the room.. I do one hole, but pick up to do 2nd it doesn't start. RCBO tripped. Same happens time after time, a few secs/ or sometimes 30secs I can do maybe 3 holes. But go to use & RCBO has tripped, time after time. I try my other drill, exactly same happens. Both drills excellent & never an issue over 10 years. I use extention from adjacent room (main part of house/ separate circuit).. both work fine.

 

Pro comes back, tests the socket I used, 25mA & trips.. as it should be he says/ no fault. Also tests rest of house.. 27mA trips/ fine.

He says it can only be the drill. But I told him I tried 2x, & ruled them out catagorically at fault if both work fine via an extention from adjacent room.

 

This is concerning: I have routers/ similar motor unit tools to use in my new workshop. impossible to work/ use it if constantly tripping.

 

thx zoot.
