You are a journeyman electrician in an industrial plant. You have been assigned the task of connecting a 25-kW electric heater to a 240-V, single-phase panel. The heater is located in an area with an ambient temperature of 90°F. The conductors are to be copper with Type TW insulation. The heater is expected to operate for more than three hours at a time. What size conductors would you use to connect this heater? Is this correct? I=P/EI=25000 W/ 240 VI= 104.17 amps x 125%I= 130.21 amp/ .96I= 135.63 amp2/0 AWG conductor will be needed
