◆ When using an isolation tranasformer, ensure that the load is balanced.
◆ When using #6 AWG wire 2 in. are required for wire bending space opposite the terminals. 1 1/2 in. for #8 AWG.
3 in. for #3 AWG and #4 AWG. 3 1/2 in. for #2 AWG.
◆ For 6KVA output configuration #1, #2, #3, #4, #5, #6, and #7 use #6 AWG, 75ºC copper wire. For 10KVA
output voltage configuration #1, use #2 AWG,115ºC copper wire. For configurations #2, #3, #4, #5, and #6 use
#6 AWG, 75ºC copper wire.
