connecting the earth wire |
|
The best way to connect a wire to a earthing terminal on a
earth clamp is with a crimping lug.
You will need to get the correct size lug for the wire that you are using and will need a suitable crimping tool, your local electrical stockist will advise you.Strip enough of the insulation from the wire so that the conducting wire fits the the top of the lug, but do not strip off too much insulation or you will see a gap between the lug and the insulation material, which will make it look amateurish.
|
|
Push the wire all the way into the lug. |
|
Place the lug in to the correct crimping location in the pliers and then squeeze the handles together as hard as possible. |
|
The lug should now be firmly connected to the wire.
Hold the wire firmly and try and pull the lug off, if you succeed in removing the lug then it was not crimped sufficiently. Obtain a new lug and try again until you cannot pull the lug off! |
|
Now remove the screw from the earthing terminal and the washer. |
|
Align the hole in the lug with the hole in the earthing terminal and replace the screw and the washer |
|
Tighten the earthing terminal screw with a good fitting screw driver.
|
|
The finished job should look like this! |
When you are bonding pipes together, for example beneath a boiler or in a airing cupboard, or bathroom it makes sense to plan a route where a single wire can be used. This single wire will connect to the furthest pipe by using a lug and then to each other earth clamp by simply removing a small piece of insulation as described below.
|
Mark both sides of the earthing terminal on the insulation of the wire |
|
Carefully cut around the insulation with a sharp knife,
making sure that you do not press on too hard.
It is advisable to wear cut resistant gloves when doing this! |
|
Now slice down the wire so that the two marks you have made are joined together |
|
Remove the piece of insulation, exposing the bare conductor |
|
Separate the strands of copper by using a small screwdriver |
|
Push the screw from the earthing terminal through the hole that you have made in the copper conductor |
|
Using a good fitting screw driver tighten the screw to the
earthing terminal, tightly.
Repeat this as many times as necessary. |
