    Strange lighting issue

    Had 2 new lighting groups installed on a multi wire branch circuit that used to be used for kitchen outlets. The 12-3 cable enters the switch box where the neutral is tied to the 2 neutrals from the lights. Hots go to 3 way switches with travelers sent to 3 way dimmers in another box. Hots are...

    Strange AC Potential

    I am trying to understand the underlying mechanics of why I am getting a voltage potential from a metal cabinet to my body. The electrical cabinet has an LED light fixture in it. I live in a very old house so there is no ground wiring. I was noticing a very slight shock when I brushed up...

    Two-way switches and strange wiring question

    Hey all, I'm trying to restore some switches in a house that's only nine years old in place of some terrible motion sensors. History is quite unknown, but considering the placement of some switches, it seems the developer is somewhat to blame for the peculiarity! All the wires behind where...

    Evening all, Went round to a clients house and did some tests on an outdoor socket. At the junction (in an IP rated wiska box) between the cable coming in from the house and the SWA running to a single outdoor double socket down the garden, the IR test between L-E fails at 0.05 Mohms. When...

    Strange voltage and power factor values and installation issues

    Hi, We have installed 2 meters (each meter is a 3 phase meter) for sub-metering in a residential house (1 phase installation per apartment). One of the meters, after correcting installation, works fine now. The other one, in my opinion measures strange voltage values. We had since the begining...

    Hi all, Had my downstairs ring final circuit trip the B32 MCB today. The missus was in the kitchen cooking and had apparently put the kettle on and as it was close to boiling the MCB tripped. I therefore assumed it would be due to the kettle so I checked the 13A fuse in the kettle plug but it...

    Strange circuit breaker activity?

    Hi there. I'm dealing with a difficult to locate problem with our 120V landscape lights. My first thought was there was a short somewhere in the run, but there seems to be something additional going on at the circuit breaker or closer to it. The circuit (one bundle of white, black, green)...
