Terminals are brass studs No. 10-32 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.
Models 460-380, 460-400, 460-416 designed specifically for 50 Hz operation are available with reduced performance - consult factory for details.
This page contains a circle diagram for the estimation of the errors for other than rated burdens.
Each transformer has two plastic terminal covers.
