(1) Select the cable with the correct current rating.
3 Amp – Cable size ≥0.5mm² (for equipment upto 700 Watts)
5 Amp – Cable size ≥0.75mm² (for equipment upto 1200 Watts)
13 Amp – Cable size ≥1.25mm² (for equipment upto 3000 Watts)
(2) Prepare the cable.
Remove cable outer sheath and trim the wires as follows:
BROWN wire 20mm long
BLUE wire 30mm long
GREEN/YELLOW wire 50mm long
3a 5a 13a fuses
Strip 12mm of insulation from each wire to reveal bare copper.
To make a more reliable connection in the plug terminals, a useful tip is to fold the bare copper strands back on themselves before putting them in to the screw terminal.
(3) Select the correct Mains Fuse.
3 Amp (Red) for equipment upto 700 Watts
5 Amp (Black) for equipment upto 1200 Watts
13 Amp (Brown) for equipment upto 3000 Watts
(4) Connect the wires into the Plug as follows:
BROWN wire to L (Live) Terminal
BLUE wire to N (Neutral) Terminal
GREEN/YELLOW wire to E (Earth) Terminal

Re-assemble the plug, making sure the clamp grips the cable, but doesn’t crush it.
Your completed plug should look very much like the one shown here.
Now you just have to screw the lid back onto the plug making sure the wires are laid carefully so you don’t pinch them when screwing the lid tight.
For any jobs which involve permanent hard wiring, you may require an electrical certificate & for the installation to be carried out by an approved competent electrician. You can call us on 0845 3883 648 for advice.
outdoor socket
When power is required for the shed, patio, garden pond or other out of doors purpose, a separate circuit from the consumer unit should be used.
Where a Residual Current Device (RCD) is not already fitted before the consumer unit, one should be installed. The Residual Current Device will switch off the electricity almost instantaneously if a fault develops in the circuit.
Waterproof sockets must be used where an outside socket is required, an internal control switch is also recommended so that the outside socket can be isolated if necessary.
There are a number of alternatives to using mains electricity in the garden, low voltage garden lights and appliances are available to reduce the risk of using electricity out of doors.
Electricity Usage Monitors
The basic figures contained within a monthly or quarterly electricity bill do not give you much information as to where your electricity is going – they just tell you how much you have used in total during that period. Therefore it is well worth considering purchasing an electricity usage monitor and using it to see exactly where all your hard-earned money is going.
If you live in an old house, you may need to think about rewiring your home. With the advice of an electrical contractor, you can go to sleep knowing your family is safe. Electrical fires are all too common.
Talk with an electrical contractor about your home.
The most sensible first step in rewiring your home is to ask an electrical contractor. If you’re lucky, you may discover that not all the electrical circuits in the house need to be replaced.
Also work out a detailed plan with the qualified electrician regarding exactly what you require in terms of socket positions, quantities of lights & electric shower or cooker supplies.
Difficulties faced with rewiring a home.
The ease or difficulty of rewiring your home will be partly dependent on the type of house that you live in. You will almost always need a lot of floorboards lifted to route cables. Walls have to be chased which can be very messy & dusty. With stud walls you can sometimes just drop the cables down the cavity of the walls.
Staying put while the electrical contractor rewires your home
When it comes to the question of staying in the home versus taking yourself away while the rewiring job is being done, the best thing to do is ask yourself how much you think you can bear.
Most clients stay at home, the rewiring can be done in such a way that the family always has in the evening, when they are home. Other people, especially those getting their floorboards ripped up, sometimes choose to take a short holiday or stay with friends.
The cost of having your house rewired by a professional electrician can vary considerably depending on how many fittings you require, the layout and size of the house and ease of access (particularly if rewiring). Nonetheless, it is of course possible to give some idea of the range of prices you can expect to pay for wiring, perhaps more so than for smaller electrical jobs which depend more on the specific location.
The cost in terms of fittings can be broken down into different sections some of which will only apply if you have a new house and others only if you are having the wiring replaced.
The average cost of a rewire from T-Lec would be around £2500 for basic specification in a 3 Bed House.
