Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit pro-
tection must be provided in accordance with the National Electrical Code and any additional local codes,
or the equivalent. The VFD shall be protected by fast-acting Class T fuses only, rated 100 A maximum.

G G e e n n e e r r a a t t o o r r S S i i z z i i n n g g : : Generator sizes noted above are a minimum recommendation.
1-Phase: Generators should be sized such that their Prime Rating for current capability (typically specified
with a power factor of 1.0) exceeds 150% of the Rated Input Amps for the SubDrive Connect Plus model
being used.
3-Phase: Generators should be sized such that their Prime Rating for current capability (typically speci-
fied with a power factor of 0.8) exceeds the Rated Input Amps for the SubDrive Connect Plus model
being used.
