NEC rules sometimes refer to "the yoke".

For example: 1999 NEC ยง 210-4(b):

Dwelling Units. In dwelling units, a multiwire branch circuit supplying more than one device or equipment on the same yoke shall be provided with a means to disconnect simultaneously all ungrounded conductors at the panelboard where the branch circuit originated.

What is meant by the term 'Yoke' as used in the NEC?

The 'Yoke' is the structural frame of a receptacle or switch: yoke

It is often metal, with holes for two captive mounting screws, and should almost certainly be grounded if a grounding conductor is present.

Examples:

  • A light switch in a single-gang junction box has a single yoke.
  • Receptacles (in North America) are often manufactured in a pair of two outlets on a single 'yoke', which can be installed into one single-gang junction box.
