Why do your light bulbs keep blowing?

Light bulbs blowing does not necessarily mean that there is a fault in your wiring as your fuses or MCB would have picked this up first.

The main reason for a faulty bulb is the quality of the bulb itself, the saying 'you get what you pay for' has never been so true in this instance. Cheap bulbs won't last long as even the smallest surge in electricity will cause them to blow. Spending a little extra on a quality bulb will save you money in the long term.

Another reason would be a loose connection between the bulb and the fitting and will cause the bulb to blow. Make sure that fittings are tight and the bulb is tightly fitted to avoid this

How to wire a plug

Wiring a plug is one of those tasks that we all face at one point in our lives, but it is surprising how many people have never done it or don't know how to do it. It is one of those questions that you feel silly asking, but you are not alone.

Below I explain how to safely wire a plug.

The terminal at the top of the plug is the Earth terminal, this is where the green and yellow wire goes (if there is one). Double insulated appliances do not need an earth wire!

The brown wire goes to the Live terminal which is connected to the fuse, which is on the right. The best way to remember which side the brown is on is to take the second letter 'R' and take this as meaning right.

The blue wire connects to the neutral terminal on the left of the plug. The best way to remember which side the blue wire is on is to take the second letter 'L' and take this as meaning left.

The Basics of Home Electrics

Plumbing and electrical systems in the home may seem as different as any two things could be. Although there are many similarities.

Water is pumped into your house so that when you turn your tap on, the water flows through it.

Electricity is sent to your home under pressure through wires using voltage that is measure in volts. When any electrical equipment is switched on (like water) the electricity flows at a rate called amperes or amps. Electricity is converted to power, measured in watts or kilowatts (1000 watts is equal to 1 kilowatt) The energy used is measure is kilowatts per hours (KWH).

Every house is installed with an electricity meter which measures the amount of electricity that the household is using so that they can work what to charge you. The meter registers how many kilowatts per hour are being used.

Homes each have 3 main lines that supply 110-120/220-240 volts ac (alternating current). The 3 wires provide 110-120 v for electrical devices such as lighting and small appliances while the 220-240v is used for devices such as tumble driers and electric heating.
