If you cannot find any ferrules, another option is to use a GFCI protected, outdoor rated recepticle and no switch. The ferrule "converts" the stranded wire to solid wire at the terminals. The ferrules are necessary because the terminals of the switch and the recepticle are not designed for stranded wire, only solid wire. This project is simple with only a few components and straight-forward wiring.Ĭrimp a 14 gauge ferrule onto each of the three wires coming into the box. This project is quick it only takes about 15 minutes to complete. This project is safe because all materials used are CSA approved, the device is properly grounded, wires are properly sized and an appropriate strain relief device is used on the cord. Other things that usually don't come with switches are soldering irons and hot glue guns. To control the pump I have to plug or unplug it, which is annoying. I am doing some experimenting with hydronic solar thermal collectors and the pump I'm using does not have an on/off switch. Now I have an extra one in case I can't find my other one or if the other one is in use.ģ)Some appliances do not have an on/off switch. Just remember to derate the power of the appliance accordingly.Ģ) No matter where your extension cord is, you can never find it. If you build one you can make the cord as long as you want. My project adds six feet to any extension cord. This neat little device solves three problems that I usually come across when experimenting or doing work around the house or out in the yard:ġ) No matter how long your extension cord is, it's always three feet too short.
