Finding the power supply feed cable

In Sweden, Norway and Finland there are four feed cables entering the electricity meter: 3 live

phases (L1, L2, L3) and 1 neutral (N). The neutral cable is usually blue and the live cables are black

or brown. Cables L1 – L2 – L3 are live and it is these that the sensors should be attached to.

Safety

You should under no circumstances connect a sensor to a cable if any of the cables lead-

ing to the meter is damaged in any way. No cables need to be cut. Do not clip any cables.

Do not break any seals or such on the meter.

Contact your local electricity supplier if you are at all uncertain about ﬁtting the sen-

sors to the correct cables. All work inside distribution boxes/consumer units must

be carried out by competent electricians.
