It might be tempting to save a few bucks on the initial cost of your microwave and purchase a residential model instead. But, when you're replacing that unit in a couple of months (and trust us, you will be), consider if that initial savings was a savings at all. Commercial microwaves typically feature higher power ratings, making it faster and safer for heating foods on a larger scale. Microwaves are also great for restaurants with limited (or no) kitchen space, and also work well for bars looking to add a few food items to their menu. Think about what you intend to microwave and how much, which will help you determine what power outage and plug considerations you need.
