    What does “general purpose” mean?

    Low voltage and medium voltage general purpose transformers are used throughout industrial, commercial, and residential applications. But what does general purpose really mean? A general purpose application is a basic application that does not need any application-specific, specialized features. For example, most general purpose transformers are used for general lighting systems, HVAC and air conditioning systems, and other general appliances.

    General purpose transformers, multiple specifications.

    General purpose transformers are commonly single-phase transformers, can be outfitted with either aluminum or copper wiring, and can be used in both indoor and outdoor applications. When looking for a general purpose transformer, it’s always important to get the model that’s right for you. Just because they’re called general purpose does not mean they are one size fits all. As always, be aware of your voltage and current requirements, installation environment, and kVA rating.
