I had to do some plumbing work today, one of the jobs was sorting out a water heater, had a quick look at it and there was nothing wrong with it visually so I took it down to the shop to be repaired, turns out one of the circuit boards and the water sensor needed replacing.
So I take it back to the house to refit it, this is a nice water heater by the way, big old 6kw jobby with a nice big red wire, nice big blue wire and a nice big green and yellow wire, go into the bathroom and there is only 2 wires

a blue one and a black one

now logic would dictate that the blue is nuetral and they need to be connected, I was a bit shocked to find it was live, seems Thai logic is slightly different to normal logic, so I had a look in the circuit breaker unit, they had breakers in there with red, white, black and blue wires spurring off of them, the nuetral bar was just as colorful, turns out my wire starts off white coming out the breaker and is then joined to a blue bit of wire for the run, probably best to turn down any electrical jobs on this building
