A 440 volts motor has a 40 amperes
full load current of 34
amperes. what size The rating of disconnecting means is 115% of full load
disconnecting means is current.34 * 1.15 = 39.1 amperes.The nearer rating is 40
required? amperes.
Continuous
a continuous load is a load expected to continue for
According to the NEC, three (3) hours or more.The installation requirements
fixed outdoor deicing and for fixed outdoor electric deicing and snow melting
