Care ought to be taken if you have one of these circuit to make sure that handiest appropriate light fittings and switches are used. Maximum metal mild fittings and switches will require earthing, but the ones marked with the double insulated image do no longer need an earth connection. Maximum plastic switches and light fittings also are safe to be used on circuits and not using a earth.
The neutral cable is a double sheathed cable (6181y with a blue inner sheath) that runs from the cu neutral busbar and from mild fitting to light becoming (there'll handiest be one neutral at the quit of the circuit).
All metal items that enter a rest room from out of doors of the room (e.G. Copper pipes, electric circuit cables) are connected together using 4mm² inexperienced/yellow insulated cord. Connection is also made to each of the protecting earth wires in every circuit that feeds an appliance in the bathroom (e.G. Lamps, heaters, towel rails and many others). That is called equipotential bonding and is designed to minimise exposure to dangerous voltages that can be present at some point of electric fault conditions. The cord is hooked up to steel pipes the usage of bs 951 earth clamps. The wire is attached to radiators the usage of connectors. It's miles approved to area equipotential bonding connections immediately outside the rest room if vital. Word equipotential bonding may be overlooked if all of the circuits that enter the toilet are blanketed by way of rcd(s) with ride thresholds of 30ma or much less. Radial circuits are used for lights. There may be one lighting fixtures circuit on every lighting fixtures mcb. Lights circuits are normally on a 6a mcb or 5a fuse, although 10a can be used (with some extra regulations (now eliminated inside the seventeenth edition of the wiring regs)) for large circuits. But if the region served is massive, extra 5a or 6a circuits would in most cases be most efficient.
