A portable or backup generator can be connected to your home’s electrical circuit by installing a generator transfer switch. As a consequence, your home’s equipment and technology are shielded harm from power surges and voltage instability.

The size, type, and complexities of the transfer switch, and the generator’s type and size, will all affect how much it will cost to install a generator transfer switch. The implementation typically costs between $500 and $2,000 or more.

The installation of a generator transfer switch should always be handled by a certified electrician since it necessitates understanding of electrical rules and suitable safety procedures.

Cost to Install Generator Transfer Switch

What is a Transfer Switch?

Transfer switch is a device that allows multiple sources of power to be safely connected or disconnected from an electric load.

A backup generator is installed in many houses and businesses as a means of backup power. A transfer switch simply flips the power from one source to another in a safe manner.

Transfer switches can be broken down into two main categories. Automatic transfer switches and manual transfer switches. They both have their own pros and cons when it comes to practical use.

An automatic transfer switch (Fig 1) automatically transfers power from your grid to your generator during an outage. Some automatic transfer switches can also turn on your generator in case of an outage.

Similarly, it can turn your generator off when the main power comes back. Hence they are extremely costly. They are also pretty hard to install and should only be done by a professional.

A manual transfer switch (Fig 2) costs significantly less than an automatic one and rightfully so. Because it does not provide you with any additional features, such as automated power transfer, or turning your generator on and off.

You have to be physically present to turn on your generator and pull the switch to swap power to your generator. They are also comparatively simpler to install than automatic transfer switches.

How Much Does It Cost to Install a Transfer Switch?

The cost to install generator transfer switches depend on several factors. The type of switch, number of circuits, amperage rating, and electrician cost, etc. The cost based on these categories is given below.

The Type of the Switch:

Manual transfer switches cost significantly less than automatic transfer switches. The average price of a manual transfer switch will vary between $200 to $800 based on its amperage ratings and circuit support.

An automatic transfer switch will cost around $400 to $2000 on average. A detailed chart is provided below.

Ampere RatingManual Transfer SwitchAutomatic Transfer SwitchAmpere Rating
30 Amps$150 – $450$200 – $50030 Amps
100 Amps$250 – $700$350 – $1000100 Amps
200 Amps$450 – $1000$700 – $1450200 Amps

Number of Circuits Supported: 

A six-circuit switches cost less than a ten-circuit switch. It will cost $350 to $400 for the switch, and an extra $200 to $400 for the electrician cost. 

Electrician Cost:

Manual transfer switches are easier to install. On the other hand, automatic transfer switches are very hard to install and can take above five hours on average.

Thus they will cost significantly more to install. An electrician might charge around $200 up to $500, depending on the reputation of the electrician, and the region.

You might be wondering, “Can I install a generator transfer switch myself?”. Yes, you can. But, only if you have the necessary knowledge and experience to do so.

It is an extremely risky task, and any minor mistakes can lead to major accidents. Hence, you should always leave it up to a professional if you do not have the necessary expertise in this field.

These are the different factors that will directly affect your cost to install a transfer switch. Let’s summarize.

Manual transfer switches will cost you around $650 to $800 on average, including the electrician cost.

Automatic transfer switches will cost you around $750 to $1000 on average, including the electrician cost.

But keep in mind, this is only an estimation. The cost will completely depend on your choices. The type of switch you choose; the number of circuits you wish to support, will directly impact the cost of installation.

Comparing Prices for Professional and DIY Generator Transfer Switch Installation 

A generator transfer switch installation may be a challenging and even risky undertaking. To save money, some householders may prefer to perform the installation themselves.

Professional Installation: 

A generator transfer switch installation by a qualified electrician might be more expensive than installing it yourself, but there are some significant advantages.

Professional electricians has the skills and instruments essential to carry out the installation in a safe and effective manner. They are also trained and experienced in working with electrical systems.

Additionally, a qualified electrician can be held liable for any damages or injuries that may result if something goes wrong during the installation procedure.

It is typically reasonable to expect that professional installation will cost several hundred dollars or more. However, the price will vary based on the complexities of the project and the electrician’s rate.

DIY Installation:

You might be able to save some money by installing a generator transfer switch yourself if you’re confident dealing with electricity and are ready to assume the dangers of a DIY job.

However, it’s crucial to understand that DIY installation might be risky if you don’t have the required information and abilities.

Having the proper tools and equipment is also essential, as is carefully adhering to any safety precautions and instructions. In general, DIY installations are less expensive than employing a licensed electrician.

If you’re thinking about performing a DIY installation, make sure to properly investigate the procedure and confirm that you have the required information and abilities before moving further.
