How to test house electrical

[Mike45]

Sorry Mike, misread your post, most aircons will be fine on 4mm² (or even 2.5mm²) so if it's that or larger no worries.

It looks like 4mm. So I guess its OK

What I can see from the photo is a green cable (ground?) 3 red cables (Live - single core?) and a white cable (Neutral - single core?). So, that's going to more than just the A/C, yah? It doesn't look 'normal' so you might just check what is it those wires are going to? (I think you said still ruffing in.)

i love all this technical talks but what i experienced in my first 2 houses was that more then 1 group is lead through the same pipe and that the colors on the wires are there to switch them.

last house have the electric system as in Germany. Every room a central box in the ceiling and all wires are there connected...then 1 pipe direct from there to the Siemens board with 1 automatic fuse for every room.

Living room and master bed room each 2 groups

All switching material from siemens

wires, in correct colors buy here local

Blue for 0, brown for phase and green/yellow earth all 2.5 mm2

Black for switch wires 1.5 mm2

forget to say... every airco 6 mm2 + 2.5 mm2 grounding with own breaker

What's an automatic fuse ?

Guessing he's referring to a circuit breaker. MCB

Assume so, but does Germany have one shared circuit per room for lights and sockets ?

Sorry for the confusion. I couldn't perch myself on the bucket and take a photo at the same time so I took a photo at the CU of wires of the same size.

The AC has three wires, white, red, green

yes 1 circuit breaker > 1 group > 1 room with 1 to the room beside. Big advance is that all is easy to follow in case of problems. The 1 room beside make that is 1 group fall off in the room is still a point for light

See the attached schedule... sorry is in dutch
