Electrical System London

Electrical Systems in London, domestic properties

The Fuse Box or Consumer Unit

The fuse box is the house or flat’s insurance against electrical fires and safety against electrical shocks. If an electrical circuit is made to carry more current than it was designed for, perhaps by running a heater from a lighting power point, the fuse for that circuit will overheat and melt if the Fuse Box is the old style or the modern fuse will be cutting off the current to the electrical circuit.
fuse box consumer unit

If an old fuse is replaced by heavier wire, instead of the fuse melting, it is the cables, out of sight, under the floor boards, inside the walls and ceilings, against wooden joists and timber that will overheat and melt. This can start a fire and fires started this way are not covered by the Insurance Policy. Upgrade your electrical system to be safe using a qualified electrician.

Circuit Breakers

Circuit Breakers are switches that turn off when overloading by current. They can be reset.
electrical circuit breakers

Fuses

Old fuses are thin wires designed as weak links in electrical circuits. In even older electrical circuits, there are usually two fuses, one for live wire and one for neutral. The standard for old electrical systems is just one fuse fitted to the live wire. Old fuses melt when overloaded, slowly with a small overload or with a big noise ( bang ) if for example two bare wires touch. ( Live & Neutral, etc )

Modern fuses called MCB (Micro Circuit Breaker) are designed with safety and practicability in mind. They detect when a circuit is overloaded with precision and trips the electrical circuit. They are very easy to reset.
fuse box modern

Modern Fuse Boxes – Consumer Units are protected by RCD system (Residual Current Device) for domestic buildings and RCBO ( Residual Current Breaker with Overload Protection ) for commercial – industrial buildings.

RCDs are designed to trip (shutdown) the electrical circuit if there it detects an imbalance in the electrical system, making the electrical system even safer.

Electrical equipment and units of measure

When an electricians is working on your house wiring or when you are buying a new washing machine, radio, TV, etc you will constantly come across references to the some units of measure. Each unit has a specific significance, and the first four electrical units bear a close relationship to each other.

VOLT, Voltage

Named after the Italian physicist Alessandro Volta, who invented the first battery in the 1800.
volta volt

Volt, often expressed simply as V, is a measure of the pressure that pushes the current round a circuit. The current supplied to domestic premises in U.K is generally at a pressure of 240V, and it may vary 14V above or below that figure. As the current moves from the live wire through the load presented by an appliance, light bulb,etc, its conversion to energy causes the voltage to drop. When the current leaves the load and returns through the neutral wire to its source at the power station, the voltage is down to almost zero.

AMPERE, Amps or A

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist.
ampere

AMPERE, Amps or A for short, is the unit used to measure the amount of current. The number of electrically charged particles called electrons, that flows past a given point on a circuit each second.Billions of electrons are necessary to make up just 1 Ampere. Amperage is determined partly by Voltage and partly by Resistance.

OHM, Ω

OHM, symbol Ω from the Greek alphabet, is the unit for measuring resistance. It is named after the German physicist, Georg Simon Ohm, who established the law that states that the current flow through a conductor is inversely proportional to resistance. This may be expressed by the equation : Volts + ohms = amps. Thous, if you know two of the amounts involved, you can work out the third.
ohm
The term impedance is sometimes used instead of resistance. There is a technical difference between these terms, but for house wiring the words are interchangeable.

WATT, W

Named after the Scottish engineer James Watt (1736–1819)
watt

WATT, W is the unit of power, indicating how much current an appliance consumes at any given moment. The relation between volts, amps and watts is expressed in another equation that enables any electrician to make any calculation it is needed for the electrical project : Volts X Amps = Watts.
Thus, if the current is 240V and an appliance requires 4Amps of current, the equation will read: 240V X 4A = 960W. Conversely, if you have an appliance rated at 1,200W, you can calculate that the amount of current needed is 5Amps.
It is customary to use the kilowatt (kW) which is 1,000 watts, as the unit of power for higher wattages.

KILOWATT HOUR

KILOWATT HOUR is the unit for measuring the total amount of electricity consumed. For example, if you burned a 1 kilowatt for exactly an hour, it will draw 1 kilowatt of energy from the mains, unit of consumption the would be included in your electricity bill.

House rewiring, Flat rewiring

old electrical installation

Rewiring a house or a flat is a major electrical project, not only because of the new electrical installation, but also for the collateral damaged caused to the fabric of the building. Floors needs to be taken out, ceilings taken down, walls chased, for the new electrical cables to be run in place, sockets and lights, all get damaged. And if that is not enough, the dust and dirt will almost require the house or flat to be fully refurbished.
rewiring

If the walls and ceilings are covered in wallpaper, it is very possible that plastering will be needed, wooden floors such laminate flooring will be taken out and not be re-used, wall tiles and skirting boards the same.

re-wiring sockets

While the re-wiring project itself might not cost too much, full refurbishment of the house and flat will involve a major budget for the works. New kitchen, bathrooms, flooring, painting and decorating, can add up to a major sum to be invested into the property.

refurbishment

The duration of works can vary, from one or two weeks for the re-wiring, depends on how many power points, lights, sockets will be installed in the house or flat, to few months for a full house or flat refurbishment.
