In this regard, does it matter which wire goes where on a light switch?

If your switch has a “LINE” marking, the always hot wire goes to this. The other connection will be “LOAD” where the load (ie light fixture) is wired. The load wire may have red electrical tape on it to differentiate.

Also Know, what cable should I use for outdoor lights? Mains-powered garden lighting Once outdoors, you should supply your lights via 1.5mm² three core steel-wire-armoured cable (SWA). Make sure that you only fit weatherproof lights that are suitable for outdoor use and that your circuit is RCD-protected.

Moreover, how do you wire a weatherproof light switch?

Power Mode: Neon ALWAYS ON when POWER is ON.
Switch Mode: Neon ONLY ON when switch is ON.

Where does the neutral wire go on a light switch?

The white (neutral) wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw.

How do you wire a light switch from an outlet?

To make this happen, all you have to do is switch the places of the two black wires. So you'll connect the black hot wire coming from power to either black screw and then connect the black wire coming from the light fixture to the brass screw. The neutral wires and the ground wire will stay put.

When would you use an isolator switch?

Isolator switches are used for opening an electrical circuit in the no-load condition. It is not proposed to be opened while current flows through the line. Generally, these are employed on circuit breaker both the ends thus the circuit breaker repair can be done easily without any risk.

Where should I put my fan isolator switch?

The isolator should be located adjacent to the fan outwith Zones 0, 1 and 2 in accordance with Section 701 of BS 7671:2008 (2015). The switch need not necessarily interrupt the neutral conductor.

How do isolator switches work?

The isolator is a mechanical switch which isolates a part of the circuit from the system as when required. Isolators are used to open a circuit under no load. Its main purpose is to isolate one portion of the circuit from the other and is not intended to be opened while current is flowing in the line.

What is a mains isolator switch?

In electrical engineering, a disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. Disconnectors can be operated either manually or automatically.

Is isolator a switch?

The isolator is a switch which isolates the part of the circuit system when it is required. Electrical isolators are the separate part of the system that is created for the safe maintenance.

Why isolator is used?

An isolator is a two-port device that transmits microwave or radio frequency power in one direction only. It is used to shield equipment on its input side, from the effects of conditions on its output side; for example, to prevent a microwave source being detuned by a mismatched load.

Does a kitchen extractor fan need an isolator switch?

Unlike the cooker switch, they can be tucked away under worktops or in cupboards. Your new kitchen might include an extractor fan above the cooker to remove the odours, steam and grease created when you cook. You will need a 13 amp switched fused spur, not a fan isolator (which are normally used in bathrooms).

Each switch, outlet, or other device counts as two wires.

What is an FCU connection?

A fused connection unit known as an FCU is an outlet from the mains containing the fuse where the appliance is hard wired rather than using a plug or socket.

Can you use a junction box to extend wiring?

If you do need to extend the wires, yes, a junction box would be needed. It must remain accessible. You've pretty well identified your two choices; if you don't want to re-run longer cables, you'll need to splice in some additional cable.

Can I run wall lights from a socket?

Re: Adding wall lights - run from an existing socket? lights need to be a lower fuse rating so you must wire this switched form a switched fused spur. then take the fuse out of it and change it for a 2-3amp one. use 2.5mm T&E cable from the socket to the switched fuse spur and then 1.5mm to the lights.

What is a fused switch?

A Fused Spur Switch is commonly used for powerful electrical appliances, such as washing machines and dish washers that need to be installed without a plug; they are also used for electrical items that need to be installed on a separate cable from the ring main, for safety and maintenance purposes.

How many times can you spur off a socket?

A spur can be connected to an existing socket, on either a ring main or a radial circuit, providing that socket does not already have a spur. That is only one spur per socket is allowed and the number of spurs must not exceed the number of sockets.

What is a 30 amp junction box used for?

A junction box is used to add a spur or to extend circuits and direct power to lights and additional sockets. Advice on wiring electrical junction box with easy to follow junction box wiring diagrams, including information on 20 and 30 amp junction boxes.

Can you run a shaver socket off a lighting circuit?

In certain situations, it is possible to add a shaver socket to the lighting circuit of the room; however it is probably best to consult with a qualified electrician before attempting this, especially in a bathroom situation.

Can you run a spur off a spur?

And you need to be certain that any point that you intend to take a spur from is actually part of a ring and not a spur already. Spurring off spurs is a no - particularly in a kitchen where the loading on sockets will be higher than anywhere else in a house.
