Saftey Breaker Switch Question

[Chao Lao Beach]

Looking at a 20Am, and looking at the 3 brands I have (of different Amps) there is no marking for In and out, I mean The live feed in and the smaller cable out.

Does it matter ?

A fuse doesn't matter, I have looked at soem old pics of prevous instualtions, and yep, one has the "live" feed in the top and the line to the item out the bottom and the air con has the live feed into the bottom and the cable to the Air con out the top of the switch.

Any idea ?

Thing looks like this.

These are MCBs, they are inherently bi-directional, if there is no marking and nothing in the instructions it matters not which end is in and which is out (opposite ends of course).

OK, well there you go, thanks fo rthe quick reply.

You might consider to use miniature RCCBs which give a little extras security?

See this thread:

A bit more expensive. A couple 100 Baht instead of the < 100 Baht that the normal ones cost.

Thanks Benq, from here it goes to a box with a RCCB, just trying to protect the line to this point.
