  • The primary and secondary terminals are #8 brass screws, one lock washer and one flat washer.
  • 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 3.0 amp BBS type fuse in the secondary to protect the transformer.
  • When only one fuse is used, it must be connected into the line side (H1) terminal wiring. This will prevent the presence of voltage at the H1 terminal for a ruptured fuse in the neutral (H2) terminal wiring for line-to-neutral connected transformers.
