Greetings,
Per NEC each load must have a disconnect switch. My question is can I use an outlet (120V or 240V) as a disconnect switch?
Thank you in advance.
NEC 2020
422.33 Disconnection of Cord-and-Plug-Connected or Attachment Fitting–Connected Appliances.
(A) Separable Connector or an Attachment Plug (or Attachment Fitting) and Receptacle.
For cord-and-plug- (or attachment fitting–) connected appliances, an accessible separable connector or an accessible plug (or attachment fitting) and receptacle combination shall be permitted to serve as the disconnecting means. The attachment fitting shall be a factory installed part of the appliance and suitable for disconnection of the appliance. Where the separable connector or plug (or attachment fitting) and receptacle combination are not accessible, cord-and-plug-connected or attachment fitting-and-plug-connected appliances shall be provided with disconnecting means in accordance with 422.31.
(B) Connection at the Rear Base of a Range.
For cord-and-plug-connected household electric ranges, an attachment plug and receptacle connection at the rear base of a range, accessible from the front by removal of a drawer, shall meet the intent of 422.33(A).
(C) Rating.
The rating of a receptacle or of a separable connector shall not be less than the rating of any appliance connected thereto.
Exception: Demand factors authorized elsewhere in this Code shall be permitted to be applied to the rating of a receptacle or of a separable connector
