The induced current flows in the opposite direction through the wings of the bird. Hence the wings experience a force of mutual repulsion. The wings spread and hence the bird flies.”
Do birds get heat from power lines?
Birds are unharmed on high voltage lines, because they touch only one wire and don’t experience voltage as the difference of potentials. The wire obviously has some resistance and the current generates some heat, so the wire is indeed warmer than the air. …

How do you wire an external socket?
You can wire an external socket in the same manner as a normal spur, by running the cable from a socket or junction box on a main ring circuit (via a switched connection unit) and mounting the socket on an external wall. Ensure your circuit has RCD protection, and that you use appropriate weatherproof outdoor fittings.
Are junction boxes waterproof?
