An extension cable takes mains power from a wall outlet to a bench, a machine or a job that the fixed sockets do not reach. This one gives 20 m of cable with a 3 x 2.5 mm section. It ends in four sockets, so several portable tools can be plugged in at one point.

Workshop Practice with the Extension Cable
In an ITI electrician or fitting shop, the cable lets a trainee run a Portable Electric Drill at a job set up away from the wall. A frame being drilled on the floor is a typical case. Lay the cable along a wall or bench edge rather than across a walkway, and unplug it before the job is moved.
Before a lead goes into use, electrician trainees test it. With a Multimeter Digital on its resistance range, they check that each of the three cores runs unbroken from the plug to every socket. They also check that live, neutral and earth reach the right terminals. An Insulation Tester then checks the insulation between the cores, and the readings go in a test log.
Frequently Asked Questions
How long is the cable and how many sockets does it have?
The cable is 20 m long and ends in four sockets. A drill, a work lamp and a charger can all run from one point at the far end of a workshop.
What does the 3 x 2.5 mm cable section mean?
It gives the number of cores and their size: three cores, each with a cross-section of 2.5 square millimetres. In a three-core lead these are the live, neutral and earth conductors. A larger section carries current with less heating over a long run.
Should the cable be fully uncoiled before use?
Yes, whenever a heavy tool or heater will run for a while. A cable left in a tight coil cannot lose heat well and warms up under load. Lay the whole 20 m out flat, then plug in.
Can several tools run from the four sockets at once?
They can, but the cable carries the total current of everything plugged in. Add up the ratings of the tools, keep the sum within the rating of the wall outlet and plug, and switch off tools that are not in use.
How should the cable be checked and stored?
Before each use, look along the sheath for cuts or crushed sections and check the plug and sockets for cracks. After work, wind it loosely in large loops and hang it up, away from oil, sharp edges and hot surfaces.
