How not to connect your cooker:

I found it during a kitchen refurb. The old cabinet had been removed and I found that the mounting screw had gone straight thru the lighting cable behind.
It wasnt the fitter’s fault - the cable went straight down the wall and then turned left for 6” to go into a light switch that some muppet had moved.

Unbelievably the light had worked for 10 years since the cabinet was fitted and nobody got a belt!

Damaged cooker cable, with very poor repair.

This I found in the kitchen. They had somehow managed to drill through the metal capping just clipping the cables to secure some worktop. When I got the cable out copper could be seen.

[This was] installed by a professional (you cannot install these alarms yourself - well known security company!)


The obvious white low voltage alarm cable sleeving on the earth wire for the alarm panel!

The live wire to the alarm is connected to the feed supply of the two pole switch, the neutral is connected to the load side. Result - when you turn off the switch all the neutrals on the central heating control circuits are live and this is why I was getting a live at the boiler connection with the switch off.

It’s 1.5 4 core SWA with EC14’s on either end (YUK) and two cores each in L & N, with a 40A breaker. The circuit length is about 10m, with no RCD protection, feeding a detached garage & utility building with several appliances (freezer, washing machines, TD etc). Good, eh?
