The Calculator determines grounded and ungrounded loads for general lighting, fastened (or fixed) appliances, dryers, cooking appliances, heating and A/C units, and the largest motor. All numeric entries are in Volt-Amperes (VA). The calculated loads are compiled to determine the total service load for a single-family dwelling.
After the service load is calculated the Calculator determines the size of the service-entrance conductors required for the dwelling. Proper sizing of the conductors is required to ensure the safety and efficiency of the service.
The Calculator is designed to be an aid to electricians in electrical load calculations and is not intended to replace Article 220 of the NEC® or the NEC® as a whole.
