Make sure that your generator is not connected to a circuit breaker inside your fuse panel since this can result in a fire. Avoid using a male-to-male connector or connecting generator to the circuit box directly.
Find out the amount of power needed by your appliance:
A variety of appliances are needed by people to run at their homes. So, it is important to find out the amount of electricity required by each device running at your home. It is important to determine this to ensure that the power sustained by the generator is adequate.

Now is the time to examine the amperage of the generator and plug type as you may be familiar with the wiring system and precautionary measures. The plug will be responsible for delivering electricity to both ends of the generator breaker. There is also an amperage marking on the breaker that will assist in adjusting the equipment when needed.
Drill a Hole:

Connecting The Generator With Transfer Switch vs. Without Transfer Switch
The most significant difference between these two methods is that connecting a generator without a transfer switch is less safe than connecting it with the help of a transfer switch. A transfer switch will be used to switch the sources of power to your house. When you switch back from your generator to a central device, the electricity from the generator shouldn’t be routed through the primary channel of the central unit.
This step is a bit critical as the electricity by the generator can be extremely dangerous if it has malfunctioned. A transfer switch will prevent any such incident. You will be more confident with it as there will be no problem created by electricity in your vicinity.
If somehow a situation occurs when immediate attention is needed, such as a power outage or electrical shortage, people wish to restore it easily as well as swiftly. That’s the reason they go for the generator to connect it without the transfer switch.
However, to do the whole process you need to prepare all needed tools including cables, interlock kit, and other essential materials. As it is a very easy and quick method, making connections without a transfer switch offers some danger to home that you must keep in mind before proceeding further.
Here are some more safety tips for you to keep in mind to minimize any harmful risk and to ensure the safety of your whole family:
- Never use any kind of male-to-male plugs as they can harm the whole system.
- Try to use a generator that isn’t linked to the circuit breaker directly.
- Without shutting off the main switch, do not attempt to make any kind of modifications.
- An interlock kit is a must thing if you want to utilize a generator without a transfer switch. As it is the only safest way of running a generator without a transfer switch.
- Have some knowledge about the laws by state and avoid doing anything that is prohibited by officials due to safety concerns.
- If you aren’t sure after attaching the generator to your house without a transfer switch, it’s a smart idea to get aid from any professional to find out the job is done accurately.
