best electical conection method

9 years ago
electrical solder, none other. and your electrician probably won't have a soldering iron. if not, buy one, it will be worth the price. if your wires are buried in a wall, underground or some difficult location, they may need repair or replacement in time. solder your wires, forget about using wire caps. twisted wires without solder can heat up with heavy current and become useless. soldering wires is similar to soldering copper tubing but requires electrical flux and solder. flux is a wire cleaner so that the solder will flow and adhere. after flux is applied heat the joint in the middle and apply solder at the tip of the solder gun or iron and it will flow to where the flux has been applied. you may have to apply a little more solder at the tip of the iron. it is difficult to solder wires side by side but can be done. it looks like a very neat joint but has no mechanical strength so twist them together in case they have to be pulled through a wall or conduit later. of course before connecting the wires together put shrink tubing at each end of the wires and then twist. once you have soldered use a heat gun of hair dryer to shrink the tubing. if your shrink tubing is large enough, apply a good insulating tape around the joint and then shrink the tubing. applying a insulating tape over the shrink tubing will dry out over time and be useless. if this is a first time laying of the wiring and it goes through a conduit don't let the electrician use any 90 degree joints, they'll be very difficult to pull through later if need be. hope this is useful to anyone
