conductors, splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space.

(B) Wire Bending Space. Wire bending space within in- dustrial control panels for field wiring terminals shall be in accordance with the requirements in 430.10(B).

409.106 Spacings. Spacings between live bare metal parts in feeider circuits shall not be less than specified in Table 430.97.

Exception: Spacings shall be permitted to be less than those specified in Table 430.97 at circuit breakers and switches and in listed components installed in industrial control panels.

409.108 Service Equipment Where used as service equipment, each industrial control panel shall be of the type that is suitable for use as service equipment.

Where a grounded conductor is provided, the industrial control panel shall be provided with a main bonding jumper, sized in accordance with 250.28(D), for connecting the grounded conductor, on its supply side,
to the industrial control panel equipment ground bus or equipment ground terminal.

409.110 Marking. An industrial control panel shall be marked with the following information that is plainly visible after installation:

(1) Manufacturer's name, trademark, or other descriptive marking by which the organization responsible for the product can be identified.

(2) Supply voltage, number of phases, frequency, and full-load current for each incoming supply circuit

(3) Short-circuit current rating of the industrial control panel based on one of the following:

a. Short-circuit current rating of a listed and labeled assembly
b. Short-circuit current rating established utilizing an approved method
FPN: UL 508A, Supplement SB, is an example of an ap- proved method.

Exception to (3): Short-circuit current rating markings are not required for industrial control panels containing only control circuit components.

(4) If the industrial control panel is intended as service equipment, it shall be marked to identify it as being suitable for use as service equipment.

(5) Electrical wiring diagram or the identification number of a separate electrical wiring diagram or a designation referenced in a separate wiring diagram.

(6) An enclosure type number shall be marked on the industrial control panel enclosure.
