5.9.14.7 Spacing. Connectors shall be spaced far enough apart so that they can be grasped firmly for connecting and disconnecting. Space between adjacent connectors, or between a connector and any adjacent obstructions, shall be compatible with the size and shape of the plugs, and the type of clothing worn by the maintainer (e.g., cold weather handwear, NBC gloves). For bare finger operation, space between adjacent connectors shall be not less than 25 mm (1 in), except where connectors are to be sequentially removed and replaced and 25 mm (1 in) clearance is provided in a swept area of not less than 270° around each connector at the start of its removal/replacement sequence. Space between adjacent connectors shall be not less than 32 mm (1.25 in) if the connector is to be operated with gloved fingers, 64 mm (2.5 in) if the connector must be gripped firmly, and 75 mm (3 in) if the connector is operated with mittened hands. Spacing shall be measured from the outermost portion of the connector, i.e., from the backshell, strain relief clamp, dust cover or EMI/RFI shield. Where high torque is required to tighten or loosen the connector, space shall be provided for use of a connector wrench.
