Powercuts can be mysterious in who they affect. Earlier this year, we had a power cut in our street but one out of the four flats in the house still had power.

Make a note of when this happened. Although 6 hours isn't enough to claim compensation from the electricity company, if it happens more than three times in a year for 6 hours each time, they'll send you 50 compensation - if you ask!

Applespider,

That flat, obviously, has a power supply from another source!

It doesn't happen to be a msteriously warm flat with quiet residents and with lots of lovely plants growing in it by any chance?

Regarding some houses/flats working while others do not... I'm not an electrician but as I understand it the electricity cable that runs under the road (or overhead if you're out in the sticks) comprises three different coloured conductor wires plus a neutral wire and earth wire. Since 2004, the three conductor wires are coloured brown, black & grey, the neutral is coloured blue and the earth is coloured green and yellow. Essentially this is better known as three phase, neutral and earth.

Usually each house in the road is served by a single phase plus the neutral and earth. So if there were just three houses in the road, then one house might be connected to the brown phase, one to the black phase and one to the grey phase plus the neutral and earth. Sometimes, when there is a problem with the power supply, it only affects a particular phase, so it is possible for one house to lose its power (phase) completely while another house continues to work ok.

The object is to spread the electrical load, since if everyone in a road was connected to any single phase then it would simply overload it. For this reason, blocks of flats might be supplied by all three phases which are then split up inside the buiding through a distribution box. So once again, if there were three flats in the block then each flat might be connected to a different coloured phase and hence one flat might lose power while another might continue to work.

Note that regardless of which of the above coloured phases supplies your house, the flexible cable connecting your electrical appliance to the wall socket will always be coloured brown, (for live) blue, (for neutral) & green/yellow (for earth) or just brown and blue. (No earth)
