In general, transformer secondary conductors are not considered to be protected by the primary overcurrent protective device. TRUE 240.4(F) An installation consists of a 10-kVA, single-phase transformer with a 440-volt primary and a 110-volt, 2-wire secondary using THWN copper conductors. No secondary OCPD is installed. The secondary loads are considered to be noncontinuous loads. Calculate the minimum size secondary conductors required to handle the secondary full-load current for this transf...
