Cord grip connectors must be used to prevent wires from chafing on the metal case and causing an
electrical short. See installation instructions for suitable connector types or call Charles Marine
Products to order a connector kit.

WARNING – ELECTRICAL SHOCK HAZARD AND FIRE HAZARD

The IsoTransformer is intended for hard-wiring in a permanent location. Cord grip connectors with water sealing
bushings and strain relief are required to secure wires or cables going into or out of the IsoTransformer.

Charles Marine Products recommends the cord grip connector kit listed in Table 1.

Various other cord grip connectors may be suitable for use with the IsoTransformer. Contact Charles Marine
Products customer service for information.

Overcurrent Protection

Overcurrent protection must be provided at the time of installation by a circuit breaker on the primary (shore) sup-
ply circuit. A two-pole shore power main circuit breaker is required for the shore power line going into the Iso-
Transformer. This should be rated at 30 amps, 120 volts, 3000 Ampere Interrupting Capacity (AIC) and be of the
long-time delay type.

A Ground Fault Protector (GFP) is necessary if a shore grounding conductor is not used. Refer to Figure 2. This
should be rated at 20 milli-amperes or less and if combined with the primary (shoreline) two-pole circuit breaker,
should be rated at 30 amps, 120 volts, 3000 AIC and be of the long-time delay type.

Making IsoTransformer Connections

To avoid serious injury or death from high voltage electrical shock disconnect AC shore power before
opening panel.

WARNING – HIGH VOLTAGE

The wiring installation will depend on the method chosen in the section titled Choosing an Electrical Wiring Meth-
od
. Follow the procedure below to make the appropriate connections.

Step

Action

1.

Remove the access cover.

2.

Install the cord grip connectors using the sealing gaskets and locknuts.

3.

Undo the chucks from the cord grip connectors.

4.

Slide the cord grip connectors down and over the cables from the primary (shore power) circuit breaker
and to the secondary (boat) circuits.

5.

Insert the cables through the cord grip connectors and cut to length.

6.

Strip back the insulation.
