Starter Modifications—Factory Installed

The general information at the top of page 1-124 regarding factory-installed modifications, also applies to those listed in the table below.

Control Circuit Fusing

Per the NEC and UL508 Section 18.2 - Control Circuit Fuses must be used when the branch circuit
protective device rating is too large to serve as protection for the control circuit. This depends on
the control wire size and whether all control circuit wires are within the enclosure. See table below:

Provide supplemental control circuit protection if control circuits with wires longer

than

12 inches are connected to branch circuit protection exceeding the ratings below

The

factory must provide this protection, if the circuit provided by the factory requires the fuses.
The factory will provide control circuit fuses in enclosed starters and contactors with pilot devices,
control relays or other control components that are factory wired; when used with line voltage
control; when the size listed below is being supplied.

Non-combination starters (CR305, CR306, CR309, CR385, CR386)

Size 4 and above

Combination starters

Size 0-3 with Mag-Break Protector
Size 3 with:
—Circuit Breaker greater than 100 amps, or
—Fuse Clips greater than 100 amps, or
Size 4 and above with any circuit breakers, circuit protector or fuse clips.

Control Circuit fuses (Modification 9) must be added to the enclosed starter or contactor pricing.

All CPTs will be supplied with primary fuses. CPTs without primary fuses are no longer available.

When control circuit fuses are not factory supplied, customer provided wiring or branch circuit
protection sizing to these contactors and starters may still require that the customer/installer add
the fusing in the field. It will be the customer/installer’s responsibility to ensure code compliance
under these conditions.
