We all dislike power blackouts especially when they happen frequently. The unfortunate thing is that we have no control over the power supply from the grid. It is a logical thing to therefore have a generator for your domestic setting. A portable one is even a better option due to the ease of handling it brings. Such equipment helps in powering your home’s electrical system even when the main power supply goes off.
However, as you think around the backup plan for your power, remember the safety of your home. A direct connection could pose more danger to the whole circuitry and electrical appliances. Therefore, the purpose is to install a generator switch. It makes you safely do the powering when need be. The main question people ask is whether one can safely do the installation without professional guidance. What is significant is follow the right procedures and everything will flow smoothly. Here are some steps to follow.
Power Off the Mains (Phase 1)
Your safety in doing the installation of a generator switch comes from following the right procedure. This is where you start by turning off the main power breaker. It makes everything you do safely. When in a blackout, remember this crucial step. Then determine which circuits are critical for emergency usage. This can include freezers, refrigerators, and furnaces.The other thing is to check on the circuit inlet of the pre-wired transfer switch. Do the right matching with the critical circuits. For instance, avoid mismatching 10-amp and 15-amp circuits. Your main target ought to be balancing the loads efficiently. There are a couple of online sites which may offer clear guidance on this. Consider removing the knockout at the panel box of the main service. It should resemble the size of the connector from the transfer switch.
Match the Transfer Switch-Knockout Holes (Phase 2)
The way you do the wire connections needs to be accurate. It prevents short-circuiting or lack of power flow. Have a sketch of the whole electrical connection at your home as it acts as a point of reference. Feed the wired into the knockout hole. As you do this, be careful not to damage the insulation. The labeling of the wires is normally done by the circuit being fed in the switch box.
By the use of a locknut and bushing secure the flexible cable from the main switch. From here, amount the transfer switch box into the wall. Let the distance between the box and the main service panel be 18 inches. Again, when wiring a transfer switch, every point needs to be well insulated. It is preferable to deal with one complete connection before going to the next step to avoid any mix-up.
Removing the Breaker (Phase 3)
Proceed to remove the breaker from the panel box of the main service. This is for the first critical circuit. At the same time disconnect the hot wire lead of the breaker. Identify the red wire and attach it to the detached breaker. Then do the reinstallation. For the black wire from the circuit, a different procedure is done.
Combine it with the old feed wire by the use of a wire connector (Preferably should be yellow). Do the tucking properly to avoid tangling. For the 240-volt circuits consider having a double-pole to which you attach the two red leads. Make the two wires coming from the transfer be adjacent to each other. Their switches need to be joined by the use of a handle tie.
However, there are times when you do not have 240-volt circuits. In this case, what is needed is the removal of the pre-attached handle tie. This makes you use the circuits individually. It means that knowing the voltage of the several circuits before you even start is necessary.
After the circuit connections, go to the neutral wire connections. This is done by attaching the white neutral wire to the neutral bus bar of the panel. Based on the brand of the main service panel, the position of the opening may be different. The task to complete the whole installation procedure is focusing on the green ground wire. This is where you attach it to the open port normally at the grounding bar in the main service panel.
