Terminals are brass studs No. 8-32 with one
lockwasher, flatwasher and regular nut.
The core and
coil assembly is encased in a thermoplastic shell and filled with
resin.
These transformers are designed for operation
line-to-line. They may also be operated line-to-ground or line-to-neutral at
reduced voltage, ( 58% of rated volts ).
It is desirable
to use a 1.6 amp fuse in the secondary to protect the
transformer.

With three
exceptions, these transformers are ANSI C57.13 group 1. Those marked * are
group 2.
Primary fuses are class CC rejection
type.
Models 460-380, 460-400, 460-416 designed
specifically for 50 Hz operation are available with reduced performance -
consult factory for details.
