How Much Does It Cost to Install Generator Transfer Switch

When you’re building your house, you’ll need the exact amount of all the costs. This is because the budget can be quite limited. That’s why you might think only you’re looking for the cost to install a generator transfer switch. But trust us you’re not. 

How much does it cost to install a generator transfer switch?

A generator transfer switch costs around $1,500 – $2,000. The cost of labor alone might be $500. Installing only one transfer switch will likely cost around the same price. A six-circuit switch will cost $250 – $300. A ten-circuit switch will cost around $350 – $400. If you buy a manual switch, then it’ll cost you less. But an automatic switch will cost you way more.

Do you feel like you still don’t have the full estimate? Don’t worry. That’s why I have this article.

Just have a read if you’re still confused!

Cost Calculator For Generator Transfer Switch Kit 

Suppose you want to know how much it costs to move a garage. You would first like to know the approximate amount it will cost to do it by yourself.

You will then search for any service that can do the exact same thing cheaper. This can be the case for the transfer switch kit too. 

The cost of installing a transfer switch is expected to be around $2,000. The cost of labor can be around $500 alone. Only one transfer switch will likewise cost around the same price.

This cost varies due to many factors. One such factor is the transfer switch type. I have differentiated the cost for Installing two types of transfer switches-

A Six-circuit Transfer Switch

Aspects BudgetAverageLuxury/Extreme
Switch Price$200$350$500-750
Total price$400$650-700$1,000-1,500

So on average, you’ll need $650-$700 to install a six-circuit transfer switch. This is the best deal in my opinion.

A Ten-circuit Transfer Switch

Switch Price$350$400$500-950
Total Cost$550-650$750-800$1,000-1,950

It’s clear now that it’ll cost you $750-$800 on average to install ten circuit transfer switches. 

You might now be asking yourself why you need a transfer switch kit. Let us explain it with an example. 

For example, a 6-circuit transfer switch can set you back $250-$300. This is for a 5000W generator. If you got a 7500W generator, the electricians will advise you differently. They will suggest that you purchase a $350-$400 ten-circuit switch.

The normal transfer switch kit has everything you’ll need to set up the switch. To put it another way, you won’t have to spend any more money on extra equipment.

But you should not presume that each and every kit contains all of the tools you require. When you buy something, read the description. It will determine if the components of the kit are worth the money.

On that note, we have recommended some good quality generator transfer switch kits-

You now have a little bit of idea how much it’ll cost you. But to understand even perfectly head down to the detailed discussion. 

Generator Transfer Switch Kit Cost: Detailed Explanation

Imagine you’re building a 2000 sq ft house. You would want to know how much it would cost to furnish a 2000 sq ft house. Similarly, when you’re installing a generator, you need the cost of a generator transfer switch. 

You should remember the cost would depend on labor and purchase cost. You will need to understand exactly how much you’d need. To do this, you need the cost of individual items. 

Let’s dive right into it. 

Labor Fees 

The first thing you need to consider is how much an electrician would charge. A transfer switch installation takes an electrician about 3-4 hours on average. Based on the electricians you selected, labor costs range from $200 and $600 or more. 

The cost of an electrician may vary depending on the intricacy of the construction. This will be determined by whether the transfer switch is manual or automatic.

Purchase Cost 

The price for purchasing will be influenced by the various models available. It also depends on the various brands, kind of transfer switch, and capacities. 

I’ll go over each one with you and give you some estimates. This way you can properly plan your finances.

The Wattage of Transfer Switch 

Transfer switches come in a variety of capacities to fit the wattage of the generator. The scale of your generator will help you choose the best switch for it. 

If your generator produces 7500 watts, you’ll need a transfer switch that handles 8000 watts. A 6-circuit switch is required if your portable generator is smaller than 5000 watts. It charges between $250 and $300.

A 10-circuit switch is required if your generator is over 5000 watts but under 1 kilowatt. This will set you back anywhere from $350 to $450. Expect to pay at least $450 for anything above that.

Items in The Transfer Switch Kit

Most respectable companies provide every necessary installation accessory with their transfer switches. This removes the need for extra component purchases. 

You will save money as a result of this. Due to this, I always advise you to read the product description before making a purchase. You’ll know exactly how much you’ll need this way.

Types of Transfer Switches 

Other than six and ten-circuit differences, there are 2 kinds of transfer switches. One is manual and the other is automatic. 

Differentiating between these two types of switches is important. Kind of like when you look at the differences between syp and spf. The costs of the two are likewise vastly different. 

Manual Switches 

Manual transfer switches are less expensive and simpler to set up. Because the electrician doesn’t have to spend as much time installing them. As a result, the labor costs are reduced. 

When an outage happens, however, you must physically flick the switches.

You might want to connect a portable generator to your house. In that case, a manual transfer switch is a logical and cost-effective option.

Automatic Switches

The cost of automatic switching is higher. An automatic switch can cost more than a thousand dollars. Personnel expenses will increase as they become more complex to set up.

An automatic switch, on the other hand, is more efficient. It changes from utility and generator power on its own. 

You can now have a continuous standby generator. This supplies power to your massive home. 

In this case, however, you should invest in an automatic transfer switch. It’s completely hands-free and automatically turns on when the electricity goes down.

Some Pointers and Suggestions 

A transfer switch is a legally recognized means of avoiding reverse feeding. Not installing a transfer switch can result in different types of electrical injuries. It can also be used as a substitute for interlock. 

I would propose a less expensive choice for a tiny home or a portable generator. That is the manual transfer switch.

Hire a trustworthy, licensed electrician for the work for the finest results. This will support you in avoiding problems with the authorities. Your homeowner’s insurance company won’t bother you as well.


Question: Is it possible for a householder to set up a generator transfer switch?

Answer: Only a trained professional electrician should set up an automatic generator transfer switch. A very good homeowner can construct a manual transfer switch. But I suggest reviewing your owner’s handbook first.

Question: Is it wiser to use a transfer switch or an interlock?

Answer: An interlock kit runs electricity from a generator to any connection inside the electrical panel. This is unlike a transfer switch, which is restricted to a certain number of connections. But if the generator isn’t designed appropriately for the load, it runs the risk of overheating.

Question: Is it possible to choose a mobile generator’s automatic transfer switch?

Answer: The answer is no. To operate a backup generator, you require an automatic transfer switch. A manual transfer switch for your portable generator will not operate.

Final Word

By now you got the full picture of the cost to install a generator transfer switch.  Because I have given you an estimation of the cost. 

But some prices might fluctuate depending on the rise and fall of accessories prices. That’s why I suggest you also have a look at the market to understand the prices.  

Good luck with your project!
