Repairing cut power cable for hedgetrimmer

EricBV

Hi all.

I am trying to repair a hedgetrimmer which has a cut power cable. I have read that there are a few ways to go about this such as using block connectors, refitting the old cable back to the appliance (if the cable left attached to the appliance is a shorter length) or stripping the cable back and attaching the wires using electrical insulation tape (which seems to be the least safest method).

I prefer to go with the second method of refitting the old cut cable back to the appliance so that the cable is continuous. I would like some advice of how to go about this please. I have managed to open up the hedgetrimmer but I am not sure as to whether I will have to keep the gold bit (crimp) at the end of the blue and brown wires. Would it be safe to strip back the longer cable at the end (the blue and brown wires) which is going to be reattached and fit it straight into the white piece and screw them down like before. Or would the crimp at the end be required? This is the first time I am attempting a repair like this so would be very thankful for any help and advice I can get.

One option might be to ask a local electrician to repair fit the shorter cable. They will have the crimp tool to remake the connection safely and will only charge for the time it takes. The main issue will be obtaining new crimp connectors of the correct size.

The crimp tools are also quite cheap, but it requires skill to operate the cheap versions.

just get m/f connector and join at the damaged area

If I use the block connection method will I have to still use the crimping tool to ensure a safe and good connection?

Will I still need to do crimping if I use the block connection method ?

I guess you are asking 'do I need to do crimping'?

Can I respectfully suggest that you leave this repair to someone who knows what they are doing?

You don't need to fit a ferrule (the gold bit at the end) it just makes it easier to fit the crimped cable into the hole in the terminal block. The easiest method has already been suggested using a pair of these. Make sure you connect the live side to the socket NOT the plug.

The "gold" ferule is probably to make the manufacturing process easier ; if a strand comes loose between stripping and screwing, it would cause a short, but a human can make sure that doesn't happen.

No need to crimp the wires, just strip back the insulation and tin the wire with a soldering iron and solder.
