As long as you follow some common sense safety rules, you can have some very handy power available for your electronic devices.It's common to describe household wall receptacles that are wired together using the device terminals as wired in series. It is a very simple process for the novice electrician. In case there is a fault with the USB circuits, it's probably better to use some cheap USB device as a tester at first instead an expensive smart phone.Īnd with that, I've advanced the electrical wiring of my house a little more into the 21st century. Since we now have a couple of USB ports at our disposal, we should also give them a test too. Turn the breaker back on for the circuit to the outlet - if you hear no load buzzing noises or smell smoke, that is definitely a good sign.īut just because nothing catastrophic happened doesn't necessarily mean things are working, As a double check, plug in something into the outlet and see if it works (in my case I just used the light that I used earlier). Attach the wall plate for the outlet and the installation is done. With everything all wired up, the next step is to push the outlet back into the electrical box in the wall and secure the outlet to the wall with the supplied screws. Also when putting the wire hook around the post - have the hook end pointing in the direction that the screw would turn when you are tightening the terminal - this will prevent the wire from popping out when tightening the terminal. Typically when attaching the wires to the terminals, have the exposed wire bent into a hook shape so that it can curve around the terminal post. ![]() Once you've identified which terminal goes to which wire, it basically becomes a process of hooking the correct wire into the correct terminal and tightening the terminals down with a screwdriver.Ī quick tip when hooking the wire to the terminals. The important thing to do is to identify what terminals do the hot and neutral wires need to be connected to, lest we blow up the brains in the outlet that control our USB ports. Remove the wires from the outlet by loosening the terminals with a screwdriver and removing the wires from the outlet.īefore hooking up the new outlet, now may be a good time to take at least a quick look at the installation instructions that came with the outlet. With the screws removed, we next pull the outlet away from the wall, Typically for houses in my part of the world, the 120 volts wiring will have 3 wires, a white neutral wire, a black "hot" wire and a bare copper ground wire.Īll three wires should be connected to the outlet with screw terminals. This is a pretty much matter of removing the screw securing the wall plate and the 2 screws attaching the outlet to the wall with a screw driver. We first start by removing the wall plate from the outlet, followed by the outlet itself from the wall. A really quick and easy way is just to plug in a small lamp into both outlet sockets - if there's no light, we are good to go. Whenever I do this, while I am fairly confident on the accuracy of the labeling of the breaker switches in my house, I always double check the outlet to make sure that there is truly no power going to it. Usually this entails pulling the breaker or fuse for the electrical circuit that the outlet is connected too. Before we start the install, we first need to ensure that the power is off to the wall outlet that we want to replace. ![]()
