1. Any fused disconnect or circuit
breaker in the incoming AĆC line
must accommodate a maximum
symmetrical AĆC fault current of
5,000 amperes.
The National Electrical Code
requires that a two pole, fused
disconnect switch be installed on
the incoming AĆC line ahead of the
Drive. Fuses for this disconnect
switch should be chosen from
Table 2Ć3. They should be dual
element, slow blow type, or
Class K5.
The disconnect switch should be
within clear view of machine
operating and maintenance
personnel for easy access and
safety. An openĆtype switch with
provisions for a padlock is
recommended.
