This is called equipotential bonding and is designed to minimise exposure to dangerous voltages that may be present during electrical fault conditions. Any electrical gadget that needs to elecfrical operated using electricity constitutes an electrical load.
This can compensate for the higher resistance and lower mechanical strength of aluminum, meaning the larger cross sectional area bzsic needed to achieve comparable current capacity and other features.
Sockets may be wired on ring circuits or radial circuits. This is why circuit breakers are also rated in terms of Amps.
The first interior power wiring systems used conductors that were bare or covered with cloth, which were secured by staples to the framing of the building or on running boards. If you try to strip wires using a knife instead of a stripper, you probably will nick the copper and weaken the wire. The Phase is invariably applied to one terminal of the switch, the other terminal moves to one of the connections of the load, and the other point of the load continues to finish at the Neutral of the supply line.

Special-purpose outlets also exist. Wiring installation codes and regulations are intended to protect people and property from electrical shock and fire hazards. This is not an ideal arrangement, as a large earth leakage fault on the non-RCD side will cause complete power failure, and sometimes inability to reset the power. Exterior cabling must be appropriate for use outside many cable types degrade under prolonged exposure to sunlight for example.
