In order to get the most out of your portable electric generator, generator accessories are an absolute must. Although many portable generators claim to work out of the box, this is usually not the case. If you lack the necessary portable generator accessories, under certain conditions, your generator may not function properly or may become damaged. A damaged or improperly functioning generator can cause injury or death. Thus, it is vital to secure the proper accessories for your generator to ensure that it remains useful to you. The right generator accessories can not only prolong the life and preserve the function of your generator but can also help you get the most out of it by making it more convenient and allowing you to use it in different capacities, such as with your RV or as a backup generator for your home when the power goes out.


A Guide to the Most Important Generator Accessories: What You Will Need to Run Your Generator Effectively and Safely

In order to be able to hook up appliances to your portable generator, you must be able to plug your appliance into the generator. However, the plug on your appliances may not fit the outlet on your generator. Also, the kind of electricity supplied by the generator may not match your appliance and may cause damage. In such cases, an adapter is an item you should definitely consider when buying electric generator accessories.

If you are connecting with an extension cord, choose an adapter that is rated with the same power rating as the extension cord so that you do not suffer a line loss in power.

Be sure to get check both the outlet on your generator and the connection of that to which you are connecting it to determine the adapters you will need. For instance, if you are planning to connect your generator to your RV, you will need an adapter that fits your generator on one end and another adapter that plugs into the RV inlet.

Transfer switch

A Guide to the Most Important Generator Accessories: What You Will Need to Run Your Generator Effectively and Safely

A transfer switch is a crucial accessory for your home backup generator or the generator for your RV. A transfer switch functions to transfer the load from one source of electricity to another source, that is, from the main supply of electricity to the backup generator. It should also be able to change the electricity load back to the main power supply when it is restored.

In the United States, portable generators which are connected to a home or another type of building are legally required to be equipped with a transfer switch. This will prevent the extremely hazardous and possibly even deadly situation of two power sources being hooked up to and feeding power into one electric circuit at the same time.

There are two kinds of transfer switches: manual transfer switches and automatic transfer switches. A manual transfer switch is a transfer switch that must be operated manually; when the main electricity supply goes out, you must flip the manual switch yourself to change to the supply of your home generator. An automatic transfer switch will switch between the two power sources automatically; it will detect when the main utility goes out and switch to the backup generator without your having to flip a physical switch and will also change the load from the generator back to the main supply once it has been restored.

It is highly recommended to hire a professional technician to install the transfer switch for you. This will ensure proper connections and eliminate the risks of fatalities from improperly installed connections.
