Main circuit breaker PTO
The in-line main circuit breaker PTO shown in Figure 43 is available
with trip ratings from 300 A to 1200 A; using L, M, and N frame
circuit breakers. This device is indoor rated and may be weatherized
upon request. See Table 46 for dimensions and ratings.
Main fusible switch PTO
The in-line main fusible switch PTO shown in Figure 44 is available
with 400, 600, and 800 A switches; using Class “T” fuses. This
device is indoor rated only. The switch handle is mounted in front,
eliminating interference with the meter sockets and the need for
spacers between the main device and meter stack. It comes with
a hinged door, giving easy access to the fuses mounted below the
main switch. See Table 46 for dimensions and ratings.
Unprotected PTO
The in-line PTO with no main device shown in Figure 45 comes
with 1200 A horizontal cross bus as standard. This device is
intended for use with six meter sockets or less or as local code
permits. See Table 46 for dimensions and ratings.
