A transfer switch is basically an electrical switch that transfers power between two sources such as a portable generator or inverter. More importantly, it allows a power generator to provide power to circuits that need it. The switch eliminates the need to run an extension cord to each individual equipment or home appliances. While a transfer switch is technically needed for powering purposes as there are other options, several factors are still present that makes it a necessity.

So what are the major benefits of a transfer switch?

Major Benefits of a Transfer Switch

Advantages of having a transfer switch can go on, but here we focused on two advantages that basically sums up all benefits.

  1. Provides power the easiest way – Technically, home appliances like air conditioning units, furnaces, and water heaters cannot be connected to a generator by an extension cords. Majority of portable generators in the market are not compatible with hard-wired electrical appliances. Which is why having a transfer switch will enable these appliances to be powered on during power outages. Transfer switches also instantly switches the portable generator on quickly and easily as an alternative power source.
  2. Safest way to connect a portable generator – Compared to extension cords, transfer switches are safer to use. Extension cords increases the risk of fires or electrocution due to a sudden back feed of power. While a transfer switch is a safer way to connect a portable generator, the hardwiring still needs to be done by a professional. 

Types of Transfer Switches: Automatic versus Manual

In this section, we will identify the difference between an automatic and manual transfer switches. The goal is for you to understand both and be able to tell which fits your needs. 

As soon as a power outage occurs, an automatic transfer switch (ATS) automatically switches the power source from the grid to the generator. It is programmable so that the power will push forward the highest priority circuits. Automatic transfer switches are more expensive compared to the price of a manual transfer switch. 

Without no further ado, Below is a list we curated to help you do a smart and informed purchase of transfer switch.
