406.4 Receptacle Mounting

Text added to recognize the generally accepted practice, that receptacles mounted in boxes supported by a pendant flexible cord is permitted.
Receptacles must be installed in outlet boxes designed for the purpose, and the outlet box must be securely fastened in place, unless the outlet box for the receptacle is supported in accordance with 314.23.

Author’s Comment: 314.23(H) permits a pendant cord to support an outlet boxes [314.23(H)], but fittings on the outlet box must ensure that tension will not be transmitted to the conductor joints or terminals [400.10]. Figure 406-1

  • Mike 314.23(H)(1) not only requires the conductors to be protected against strain, but it also requires the connector, protecting the conductors against strain, to be threaded into the a box with a hub. The threaded hub required by 314.23(A)(1) would have be part of the box, in Figure 406-1, the 4 square box shown is without a threaded hub.
