How to Use a Generator without a Transfer Switch!

Step 1: Get The Following Materials & Tools To Start The Connection!

When you are dealing with electricity, always be prepared with the right tools. Once you know everything is within reach and safety measurements are right, half of the job is already sorted.

Of course, you’ll need patience and the right guidelines later. But having all proper gears will always be a sweet start for such chores. If you want to know how to connect generator to house safely, be sure to give this step enough importance.

Interlock Kit: You need to get an interlock kit. This would help you to connect the generator without a transfer switch. But be sure to get one that matches the model of your generator. It needs to be exactly made for your version. Good news is these kits are very budget-friendly and you can get them anywhere easily.

Breaker: You need to focus on what type of generator you have. Get yourself a breaker that will suit your home specifications as well. A two-pole double breaker with 30 amp power should meet most generator specification.

Wires: This depends on the area of property you have. Get at least three sets of electric wires. These should be 10 feet of 10 gauge wires. Dealing with electric wires is no joke and can be intimidating for the novice. But if you promise to have a little patience I’m sure you’ll make it. Be sure to get different colors. This way you’ll be able to identify quickly while working.

Safety Measurements: You need to care about safety also. Since you’ll be dealing with electrical elements, don’t mess with this instruction. Wear a good pair of work gloves. Get protective eyewear to avoid any damage to your precious eyes. Also, wear work boots that will keep you safe from getting electrocuted.

Other: Now rest of the tools are really common ones. Keep some screwdrivers, pliers, wrenches, electrical tape, a huge-bit-drill or chisels, and such usual electrical gears.

Step 2: Figure out Plug Type & Amperage

You need to have a generator with a huge round plug to work with such setup. It should fit the plug both sides of breaker. You can find the amperage close to plug. You are going to find some codes as well. Read them well and adjust the materials depending on these codes.

Step 3: HoleDrilling!

You need to drill a hole that would serve as an accessible one. This hole would aid you to pass electrical wires inside the house. You should drill a big hole to make sure the wires pass and fit properly. Try to find a spot far from your generator. You need to keep it as distant as possible. For too thick walls, one should use a hammer drill. They really help!

Step 4: Amassing Different Elements

This is the most important step where we do real work. Try to mount the power inlet box far away from your home. You should keep it at least a few feet away on the exterior wall. Check and ensure the hole is watertight. Get the conduit and assemble it. Using some glue you can ensure attaching them properly. This is important to keep things safe.

Next, you deal with generator inlet plug by wiring them. Pull the wires one at a time from the conduit body. Simply fix them to the plug. One easy way is to eliminate .75 inches of insulation wire. Use a screwdriver to tighten the end swell.

One thing to keep in mind is that black means X or Y, white is common and green is for ground. You should next prepare the breaker box. Simply push all the wires inside. You should turn off the main breakers and branch properly. Place the wires on upper right spot by making enough room. Now you can easily install the wires and breaker retainer. Finish it off by covering it again.

Verdict

You should only use an interlock kit to use a generator without a transfer switch. That’s the only right way to deal with such a situation. Don’t try methods that might be illegal in your states. Those are not right for safety and can bring risk to your property. If you still feel confused about how to hook up generator to house, get help. Try calling an electrician who can do things for you. Hopefully, you now have a better idea. Good Luck & Be Safe!
