Terminals are Brass Studs No. 10-32 with one lock washer, flat washer 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.
Each transformer has two plastic terminal covers.
This page contains a circle diagram for the estimation of the errors for other than rated burdens.
