When dealing with fixed electrical installations, whether permanent or temporary, we have rules and regulations to apply, with a view toprotecting the user of electrical installations.
There are service professionals, electricians, locksmiths, carpenters, bricklayers who, naturally, use electrical equipment, sometimes in proper working conditions (double insulation), but whose plugs have been removed to allow use in “any type of electrical outlet”. ” and not hooked onto the buses! It is wrong, no doubt, but it is the reality.
TheGFCI (Ground Fault Circuit Interrupter) is nothing but a portable DR switch that is inserted between any socket and the machine tool (electroportable) and has a sensitivity of the order of 6 mA to 10 mA for leakage currents, capable of withstanding load currents of the order of 15 A.
Obviously, this is not mandatory equipment, nor does NR 10 mention the device, but there are companies that, aware of the importance of its application in installation, maintenance and conservation work in third-party facilities, over which they do not have control, provide the devices to its employees, with instruction and commitment to always use them, in order to guarantee protection against shocks.
The use of GFCI outlets can help in making electrical circuits safer. These outlets break the electrical circuit in case of problems with the wiring.
Wiring a GFCI Outlet is not technical. You just need to have an understanding of the wiring to get through. We cover the wiring of the GFCI outlet in detail in this article.
Step 1: Disconnect the electric supply to the room/area where you want to wire the GFCI Outlet. Use an electric current meter to measure the current flowing through it. Such precautions are necessary to ensure safety.
Step 2: Check your electrical box for different types of wires. Depending upon the electrical box type, there can be one hot wire and one neutral wire with a grounded metal box; two hot wires, one neutral wire, and one ground wire.
Step 3:Now grab your GFCI Outlet. For one hot & one neutral wire electric box, you have to connect the neutral white wire with the lined side silver narrow screw. Similarly, the bare ground wire should be screwed to a green screw (if you have any, otherwise the entire box will be grounded already).
A tip here: White and green color wire represents the neutral and ground ones, and the ones other both theses colors is the hot wire.
Step 4:Connect the hot wire to the brass screw usingwaterproof solder wire connectors. Wrap it clockwise to get the right functionality.
Step 5:Once the hot, neutral, and ground wires are connected, tuck the wires in the metal box and tighten the GFCI inside.
Step 6: Turn on the power. Press the reset button on the GFCI. Check the connection with the outlet tester. You have your GFCI outlet wired.
