This is actually a sub-article to a larger project article and it includes some items from previous articles. However, I think there is a solid case for writing this article as a stand-alone. Wow…mouthful of word salad!
So there I was…time to finally upgrade my water well system to a solar pump water well system. You can read more about it here <click here to read about it>. It came time to do my wire splicing…and that is where this article came from.
During an emergency, disaster, or grid-down event you may find yourself having to do some electrical work. And if you find yourself having to do some splicing it would be nice to have the needed supplies on hand. Here are a couple of things that I feel could be invaluable in those situations.
Let’s start with the basics…Electrical Tape –
Not all electrical tape is created equal. And let’s start this off with a general statement…you get what you pay for. That means I buy Scotch brand electrical tape, or private label electrical tape made by Scotch. I don’t buy the knock-offs or the cheap stuff. Why? Because I am entrusting personal safety and/or my house and/or my equipment to this electrical tape…I don’t want cheap-junk vs expensive-quality. Nice thing is…the quality stuff isn’t really that much more expensive.
I keep three basic types of electrical tape on hand; 1) Scotch 700, 2) Scotch 2242, 3) Ace 30986.
Scotch 700: A high quality, vinyl insulating tape. Resists a wide range of chemicals and abrasive materials. Can be used indoor/outdoor and even below ground. And a roll has about 66’ on it. It is good down to about 15 degrees or so. Pretty much a general purpose electrical tape that I would use where the tape is not exposed directly to the weather and not exposed to moisture…so basically dry indoors. Don’t over stretch this tape when using.
Scotch 2242: A high quality general purpose rubber tape. Used correctly it provides an immediate moisture resistant seal as well as insulation. This is a great weather resistant electrical tape. Stretching doesn’t really affect this tape. Since it is made out of rubber it is pretty dang resistant to abrasion. It is good down to about 0 degrees. A bit more expensive and only 15’ on the roll. This what I would use when the job was exposed to the weather or on my equipment (i.e. tractor) used outside.
Ace 30986: Self-fusing, water-tight, rubber based electrical tape. It seals based on a rubber resin, “vulcanized” as my electrician buddy explained it to me. It is pricey but well worth the money when a water-tight seal is needed. This is the tape I used to protect the splices on my well pump installation. Yes, that means the splice was submerged in water…and will be for years to come. I used multiple layers, medium stretch, pressed together hard.
I also keep two types of Gardner Bender Liquid Tape on hand; 1) the brush on variety, 2) spray on version.
Brush on version (GB LTB-400): It’s a rubber based brush on electrical sealant. It can be sued indoors/outdoors and creates a waterproof seal when used correctly. It’s also very UV resistant which is nice here in Arizona. It is resistant to chemicals, solvents, and saltwater. It is dry in 5 minutes, fully cured in 24 hours. Can be used in harsh temperature conditions…30 degrees below zero to 200 degrees above zero. And it stays pretty dang flexible. I like it when I use butt connectors and want to make a water tight seal around them. If I wanted a really good, virtually fool-proof water tight seal I would use the Ace 30986, then use two coats of GB LTB-400 allowing 24 hours between coats. First coat of GB LTB-400 would overlap the Ace 30986 tape ends. Then the second coat of GB LTB-400 would overlap the first coat of GB LTB-400. WARNING: don’t think an opened container of the GB LTB-400 will be acceptable for storing! Once opened it tends to dry out. Store a brand new, unopened container.
Spray on version (GB LTS-400): This is kinda like the brush on version, but not entirely. This stuff is vinyl based vs rubber based and is much thinner obviously since it is sprayed on. Yes, you can spray on multiple coats to build up the thickness. It dries quickly (5 minutes) and is fully cured in 24 hours. It is very protective and insulating but I would not count on it being water-tight with a single application, more like water-resistant. Water-tight if you build up multiple, correctly applied layers, each of which is allowed to properly cure. Can be sued indoors/outdoors and a temperature range of 30 degrees below zero to 200 degrees above zero and resistant to chemicals, solvents, and saltwater.
So there you go…there is my electrical prepper kit for electrical work.
