A metric unit of electric current equal to 100 amperes, represented by the symbol hA. While valid under the International System of Units, this multiple is rarely used in practical electrical engineering. Technicians and engineers strongly prefer expressing currents in standard amperes or kiloamperes to avoid conversion errors and maintain consistent notation.
Heard on the job
The main feed is drawing about two hectoamperes, but just write 200 amps on the inspection report.
