Disconnect Mounting Space

Disconnects are located by dimension E1. Wiring space W1 is available when disconnect is installed in the enclosure.
See the Hoffman Specifier’s Guide Technical Information chapter for E1 Spacing by Enclosure Height for various disconnect switch manufacturers.

Refer to National Electrical Code^® 2005 article 430.10(B) for wiring space required for line side conductors to be connected to disconnect. Verify your application to determine if wiring space is adequate.

Consult Space Occupied by Disconnect drawing to determine whether the disconnect device you are using will fit the enclosure size you have selected.
