Can 480V be single phase?

480V can be classified as single and 3 phase circuits. 480V 3 phase circuits are the most common power systems used in US industrial plants and are considered to be low voltage power systems.

How many wires does 480V have?

480V can be achieved by high leg delta, four wires + neutral wire which provides 480V-415V-240V or open-delta configuration. Additionally, it can also be achieved by three wires without neutral as 480V-480V-480V.

Does 480V have a neutral?

480V 3 Phase Delta is a 3 Wire power configuration and does not include a neutral wire.
