I was asked by my sister to change some surface mounted boxes for recessed ones. not a large job. Two double sockets. i asked her to turn off the sky boxes before power down and I looked at the fuse board to see just one circuit breaker -30 amps for the entire house so I switched off. I went into the kitchen and noticed the fridge was no longer humming- safe you might say?
Well as a double precaution I always check for voltage and used a martindale in the socket instead of a voltmeter. I was shocked - so to speak to see three green lights illuminate as I switched the socket on. On further investigation i discovered that underneath the surface mounted box there was a single recessed metal box complete with two cables serving the double socket, this must have once served an upstairs immersion heater and must of once been a fused spur of some discription.
I'm so glad I was cautious enough to test the socket . Any of you fellas done something similar after "safely isolating"??
