Extension cord splice
« on: March 24, 2017, 10:03:14 PM »
Hey guys. Long time no post. I'll update you on what I've been doing for the last 3 years some other time. I'll get straight to my question.

I have an extension cord I don't want to throw out. My dog chewed through it in a couple of places. What's left is worth keeping but I want to splice the two good pieces together with a quality splice. I don't really care for the "twist the wire and wrap with electrical tape" approach if there is a one piece splicer available. I don't mind shrink tubing. I don't want to use electrical tape that's just going to come off.

Holy crap, Phil. 18k posts?

My method is:

Outer shrink tubing installed first allowing 2" overlap over the cut back insulation sheathing
Shrink tubing installed on each wire prior to soldering the bare wire
Soldered twist connections (where the twist is longitudinal)
Staggered connections
Buildup using electrical tape to come up to sheath thickness, with a single wrap of tape to 1" past the outer splice
Slide outer shrink tubing into place > Heat

Attach the blender and add margarita mix to suit.

This is the best way in my opinion. Another option would be to use an inline coupler. A device that looks like a male and female plug that have been connected except it is just a round plug that is a wired in connection which on the downside leaves a big old knot in the middle of the cord.

Where would I get such a coupler? A knot in the middle of the cord is not an issue. I want a quality splice.

Should be able to get one at any big box store like Lowes. Or really any decent hdw store or electrical supply store.

why not just put male/female ends on it and make two separate cords?
Started with nothing and still have most of it left.

I use this method also.

I do like this 3M Temflex 2155 Rubber Splicing tape, self fusing tape. Amazon carries it.

Good to see you back Cornbread boy :)) :))
There is a very fine line between a hobby and a mental illness.

Does the need justify the want ? Or does the want suffice?

Because it would come apart if I pull on it and it's not a terribly long cord. It's too good to throw away though. I've got enough cords that I'll probably keep this one as is. You never know when I need a power cord for something.

I now have 3 rescue dogs in the Seattle area. Two just flew in on Wings of Rescue this weekend. One went to Humane Society Tacoma-Pierce County and the other went to Kitsap Humane Society. Now I have other reasons to get back up there besides The Buttered Biscuit. That place alone would be worth the trip.
