How Much Does It Cost To Install Generator Transfer Switch

A transfer switch is an electronic system that allows power to flow from one source to another. Its purpose is to allow your generator to power specific circuits while preventing it from back-feeding the power line.

Furthermore, a transfer switch eliminates the need for extension cords. It’s the safest way to power your home while staying compliant with generator installation regulations.

It all focuses on the generator application you’re using. Hire a professional and certified electrician to create a shift switch for you if you wish to do so.
However, this is only relevant for permanent standby generators; portable generators wouldn’t need a permit.

How Much Does a Generator Transfer Switch Cost to Install?

Depending on the type of transfer switch you choose, installation may range from $500 to $5,000. However, this cost is well worth it in the event of an emergency.

So, before you make your purchase, be sure to do your research and assess all of your options. Additionally, be sure to have a backup plan in place in case of an unexpected power outage.

If you’re in the market for a new generator transfer switch, there are a few factors you need to consider. First and foremost, you’ll need to decide how large the switch will be. You’ll also need to factor in the cost of installation, as well as the cost of maintenance.

Finally, you’ll need to budget for future upgrades and additions. In this article, we’ll provide you with a comprehensive overview of all these factors so that you can make an informed decision.

Unique aspects and factors impact the selection of installing a generator shift switch. They determine how many you’ll need and how long it’ll take you to finish the assignment.

The cost would’ve been determined by how much you spend on the product and how much you spend on labor.

1) Labor

A shift switch process will take an electrician about 3-4 hours on average. Depending on the electrician you appointed, labor costs range between $200 and $600.

Depending on the type of transfer switch, manual or automatic, the electrician charges can vary depending on the installation.

2) Purchase price

The cost of purchase will be influenced by the various models available, as well as the brand, form of transfer switch, and efficiency. I’ll talk over each one with you as well as give you some excerpts so you can start planning your budget.

a) Wattage of the transfer switch

Transfer switches are available in a multitude of capacities to accommodate the size of the generator.

The size of your generator will recommend the right switch for it. If your generator produces 7500 watts of power, you’ll need a transfer switch that can manage or over 8000 watts.

A 6-circuit switch is expected if your portable generator emits less than 5000 watts. It ranges between $250 and $300 in price.

A 10-circuit switch, which costs between $350 and $450, is needed if your generator is over 5000 watts but under 1 watts.Be prepared to spend $450 or more if you’re above that.

b) Item in the kit

Most reputable manufacturers use all the required installation accessories with their move switches.This removes the need for extra parts that save you money. As an outcome, I always advise you to scan the product description before buying a product.

c) Kind of Transfer Switch

There really are two types of transfer switches: manual and automatic. The costs of the two are also drastically different. Besidesan automatic transfer switch, a manual transfer switch is less cheapand easier to enable.
A mechanical transfer switch is a rational, albeit cost-effective, option if you have a portable generator that you want to attach to your house.
If you have a permanent standby generator that powers your massive house, however, you can invest in an automatic shift switch. It’s completely hands free and immediately flips when the power goes out.


What are the benefits of having a generator transfer switch?

Provides an uninterrupted power supply to all appliances, TVs and lights in the house during an outage to prevent harmful fluctuations from happening with someone coming home or your family waiting for you to return at nightfall.

Don’t get caught stranded like that again! Just imagine being in panic mode when you come back only find darkness around your house because your power went out.

A GTS also reduces your energy expenses since you are not paying for electricity when there is no need to run the big generators in a standby mode because technically, there is no load on them.

So moving from one state of operation to another with it operating almost costs nothing unless unfavorable conditions arise such as wind being too strong or something similar – then only those who do not have fuel powered backup equipment can feel that.

Running your generator for free is a nice thing to have, and of course by generating you would not be running the engine more than it needs just to keep the generator’s speed belt operational at all times in order that they are always ready when needed.

What are the different types of transfer switches?

There are two major types of transfer switches: One is the manual, which transfers power between electrical sources when there’s a use current on one and no net load on another.

The other type is called automatic; they work like solar inverters but can operate off if you have standby battery banks connected to them or just some generators.

But most times, transferring from portable batteries (that recharge during night hours) through several power inverters won’t be enough to provide the exact amount of electrical power you ever use.

Therefore, a generator might really come up for such cases, but fuel powered ones can only function if there’s at least one good battery bank with it in order that the engine does not just consume its own generated electricity generating no more electricity out of them from their batteries.

Also, most portable generators don’t even have standby battery banks, so they will like those that are inside of houses or would be supplied by power lines have to have their battery recharged the moment electricity gets restored.

What are the limitations of a generator transfer switch?

There are a few limitations to transfer switches:

1. Transfer switches don’t provide a way for excess electricity to be sent out over and above demand at the transfer rate of 10, 20 or 50 amp-hours (in other words, “cycles” per hour.)

2. You can only run one generator on each transference switch, which means they won’t allow you to have many generators if any, but maybe like just 1 or 2 portable generators connected between your power source(s) and the transfer switch.

3. If you have a large house with many solar generators, lighted by LED bulbs and other heat sources (for example ice machines) then transferring all that power through your generator could take hours or even days to reset back on full.

When there’s use requirement during those times of day from these appliances since their batteries aren’t getting recharged while they’re running at night while being transferred; except if they ‘re on their own standby generator in case of power failure or some other reason.

4. If you need to transfer a great deal of electricity through your generators, it could take a long time since the voltage can drop due to all that extra amps (current) being sent over and above demand.

For example, different electrical appliances, especially heaters connected with LED lights, may generate over 50 amp hours per day, but if they’re hooked together via lighting or other appliances, then the demand might have them running all the time.

5. Purchase of a transfer switch can be costly and may not pay for itself in saving money after operating cost input is factored into wires, battery replacements, etc.

6. And more difficult to set-up since some do not come with directions with pictures/diagrams showing how to hook it up plus what wire amounts to use.

Can I install a generator transfer switch myself?

Yes, you can install a generator transfer switch yourself. There are a few things you will need before you start, including a generator, a transfer switch, and some wiring.

The first step is to find a location for your transfer switch. You will need to make sure that the transfer switch is accessible and has enough room to accommodate your generator.

Once you have found a suitable location, you will need to measure the distance between the generator and the transfer switch.

Next, you will need to cut the necessary holes in the wall and install the wiring. Finally, connect the transfer switch to the generator and test it out to make sure it is working properly.


A transmission system is a legally recognized way of detecting back feeding, which may cause serious injury or death.It can also be used as a substitute for interlock.

I could prefer the manual transfer switch for a small home or a portable generator because it is a fewer expensive option. Employ a reputable, certified electrician for the job for optimum quality. This will assist you in preventing problems with.
