Depending on the model of the power supply device and the circuit of the introductory panel, the connection of the generator may differ slightly in detail.
There are known differences between manual start and automatic start, the nuances of connecting one and three-phase generators, but in general, if you have minimal skills in working with electrical circuits, you can do everything yourself.
Well, if you understand the principles of the electromagnetic starter and relay operation, you can establish autostart and a conventional generator without using a key.
“Urgent” connection methods and their disadvantages
Usually “urgent” methods are used in cases where for some reason it’s impossible to use the generator directly – you need to include it in the home network urgently, and there’s no time to mount a separate connection scheme.
The most common way to connect a generator to your house is to simply plug it into a jack, you can use a mobile socket for that. This method is strongly discouraged, but its ease of use has won over many small and medium generator owners over and over again.
The principle of using such a connection becomes clear if you look at the standard home wiring diagram. Indeed, if a current source is connected to one of the sockets, then the voltage will appear on all sections of the circuit.
Connecting the generator to the switchgear
This is the most correct way to quickly connect the generator, but it has some nuances that must be taken into account.
The easiest way to make such a connection is when there is a jack next to the switchgear – sometimes they’re installed in case of repair work or just for insurance.
Actually, in this case, you need to imagine exactly how this outlet is connected. In this case, everything depends on the throughput of the jack itself (16 Amperes) and one must remember to turn off the input machine.

The main thing here is not to confuse which machine must connect to. If suddenly there is access to the input machine before the meter, and the generator is connected to it, then the whole circuit won’t change … I’ll just include an electricity meter, which doesn’t care what to count – the current from the mainline or made by the generator.
However, there are low chances to make such a mistake, since the meter and the input machine are sealed by inspectors from the energy supervision. Since the wires from the mainline are folded back, a control lamp can be connected to them – when it lights up, the generator can be turned off. In this case, the introductory machine must be left on.
Connecting a generator through a rocker switch
In fact, this is the same connection of the generator to the switchgear but already equipped with a stationary three-position switch so that you don’t have to take the wires off from the terminals of the circuit breaker.
The very principle of the generator operation assumes the periodic occurrence of static electricity on its casing, therefore, all permanently installed devices without fail need a separate ground loop.
The ideal option is to create a full-fledged grounding loop, but really, you can do it in the simplest way, for which you need a metal rod, 1.5-2 meters long, a steel bolt or clamp connection, and a soft copper wire.
A bolt is welded to the iron bar, and the pin itself is hammered into the ground for its entire length. The copper wire is screwed with one side to the bolt (or clamped with a clamp), and the other to the generator body – the grounding is ready.
These are all the main ways to connect a generator to the home network and all possible nuances. Of course, when installing each generator, ATS unit, or homemade autorun system, additional questions may arise. But they’ll have to be solved in each case separately, depending on the model of the device and the scheme of the home electrical network.
Q: Which is better: a transfer switch or an interlock?
A: No matter which method you choose, for legal and safety reasons, it is always best to consult an electrician before purchasing or installing any components. Knowledgeable personnel will also be able to help you correctly identify the right capacity devices for your electric demand.
Q: Is it okay to install a DIY transfer switch?
A: It is not recommended to install your switch for several reasons. If you are not a licensed and trained electrician, the best bet is to leave it to the specialists to care for you. They will do a good job and eliminate all worries.
Q: Is there a good place to find and buy transfer switches?
A: As with moth items these days, the best bet is probably to look for a switching provider on the internet.
