Start with this prepared list of appliances. We have populated it with common appliances using average loads and runtimes based on our design experience.
Add extra fields by selecting the 'Add Appliances' button and scrolling through our list, or just type in your appliance or medical device. Most of the drop-down listings have the average loads filled in, so you need only add the estimated hours of use and number of days used per week.
Some items are not used every day - the calculator automatically calculates the watt hours per day over the entire week. For example: if you only use your hair dryer three days a week, it will spread the calculated watt-hours over 7 days. Clicking 'More Information' provides insight into how this particular load is calculated.
