Electric cord repair

Feb 01, 2017 25 Replies

I have a vacuum cleaner cord with a cut in the insulation. I could cut the cord short and use with an extension cord but I was wondering if it is acce ptable to cut out the bad part and use insulated butt connectors to join th e ends and wrap the joint with electrical tape. I've never seen it done so maybe it's unsafe?


Most definitely NOT. Buy a replacement cord (the right one, not an extention cord) and have it replaced properly. What make and model is the vacuum.

I'd consider cutting the cord short and put a new end if it would not cause a lot of problems in use.

How bad is the cut? If minor just on one side I'd tape it up, but only if it can be done safely.

As long as it's not a retractable cord putting on a new end would work

- if it's done right. Vacuum cords take one heck of a beating - and short ones even more because you are always at the end of the cord, putting stress on the plug.. I've always been of the opinion that a $20 OEM replacement cord is cheap insurance. I've occaisionally fitted a cord from something else depending on the machine and how it is fastened to the machine - but often the McGyvering required makes the original cord a bargain - assuming it is available. I've done some old retractors where the original part was not available, and it took some searching to find a flexible enough cord that would handle the current and still retract smoothly.

It isn't retractable. In the past, I've cut the cord, put on a new plug and used an extension. That works, but having a connector and plug is kind of bulky; that's why I was thinking of butt connectors. I'm curious as to why that is not acceptable?

Just think about "what could go wrong". It's not an idiot-proof connection.

Cuz no one will be getting any of your money....

Because there's the possibility you will not produce a safe repair. It is always advisable for others to suggest the safest repair method since asking a "how to" question in this group implies the assumption one doesn't have the proper knowledge to ensure proper repairs.

As for me, without knowing the extent of the damage and assuming it's an exposed wire, I'd repair it because I know how and have done so often. Though, that's irrelevant since you've already made the repair.

Other than for underground wiring connections, which are about like a skinny cigar tube and have clamping screws and silicone gel to weatherproof them, I don't recall seeing butt connectors rated for household voltages. All that I have or have seen were for low voltage use.

Just replace the cord. BTW, if you look for it, you can find bulk electrical cord made for vacuum cleaners (obviously flexible for the retractable units). I once bought some for one of those older Cord-O-Matic extension cord reels.

Heck, even Amazon.com has generic >30' replacement cords with molded plugs for around $14

You have seen very many then. The common vinyl insulated butt splices are 600V rated. Some of the nylon type are 300V, some 600V. non-insulated butt splices are just a copper tube. Do your own insulating.

Or the OP could use a Western Union splice and shrink tubing. That would hold up better if you drag the vacuum around by the cord.

I have used many of them on 120 volt AC circuits where I worked. They were rated for 600 volts. Even Lowes has them at thie voltage rating.

If it was my vacuum I would probably cut the wires in a staggered lengths and solder them together and use some heat srink tubing as I have this equipment in my house. If only butt splices and tape were around I would use it. However for those that have to ask, I would go with a new cord.

Guess the main questionfor me is how did the cord get cut in the first place ?

I suspect the writer of this spam knows he's using an invalid sig delimiter. That way, unthinking posters become spammers too when they quote the post.

Its only $14, but it's not here now. That gives the electrical tape a BIG advantage.

BTW, tape does lose its stickiness with age, then you can use more tape.

My parents had just bought a good vacuum cleaner with a long cord. Then the dog shortened the cord.

BTW, it wasn't plugged in at the time.

I use Avast too, it is easy to kill that signature.

He is either a willing spammer or he is too lazy or stupid to remove it, and since there is no benefit to responding to spammers, idiots, or lazy people, it is a clear invitation to disregard anything preceding it.

As long as the insulation of the inner conductors isn't affected - -

Would have taught the dog a lesson if it was - -

Yes but you must have the completed repair inspected and approved by your homeowner's association chief electrical safety inspector before returning the vacuum to service.
