Ring main

[stubuzz]

Do Thai house use a ring main or is every light connected separately from the fuse board.

[Crossy]

No ring finals in Thailand.

Lighting and outlets are wired as radials, up to 10 or so double outlets daisy-chained on a 20A breaker wired in 2.5mm².

Lighting in 1.5mm² on a 10A breaker.

Older homes may have lights and outlets on the same breaker.

I have just changed the ceiling rose and it only has 2 wires. It looks like the circuit is looped from switch to switch, as apposed to the UK where the ceiling roses are are connected.

Sound about right? It is an old apartment-circa 1970-80.

In Thailand, the locals like to feed the switch, which is indeed why you only have 2 wires at the light.

It's actually common practice now in the UK.

There are a few methods that can be used, depends on type of property and cable used.
