In current terms, the current that flows out in one conductor flows back in the other, which means it is more naturally described as "single phase". Consider first a single phase cable with a current I going out in one conductor and back in the other: We are interested in the field a distance r away. They have a single phase with a single alternating current and a contracted power of up to 10 kW. When r is large compared to the separation of the conductors d, the field is given by. We can create any combination you need. Note: on a three-phase system, you supply a single-phase load by connecting it across two of the three phases. Every other appliance is operated off of 120 volts of electricity, which is only using one hot wire and the neutral. telephone 0845 7023270 or email [email protected].

Description : 2.5mm x 3 core Single Phase Armoured Cable per metre. Phase, neutral and ground wire visible. But that's with three conductors instead of two, taking up a total width of 2d instead of d. In practical terms, the field from a single-phase and a three-phase cable at the same voltage are going to be similar, but given that the conductor spacings vary and the loads can be quite different, you can't really generalise about which is bigger, and need to do a specific calculation for each cable. So in voltage terms, it is two-phase: each conductor has a voltage on it, and neither is at earth potential in the way that a neutral conductor at low voltages is.
