STANDATA Electrical Code Bulletin: Section 26 – Installation of Electrical Equipment
Jan 15, 2021
Rule 26-600 Location of panelboards
Concerns were expressed with the requirement for mounting panelboards in dwelling units with no overcurrent device being more than 1.7 m above finished floor level. This could create a situation where the non-metallic-sheathed branch circuit cables may come within the 1.5m from the floor described in Rule 12-518.
The rationale for Rule 26-600 is for panelboards to be located in areas where they will not be subject to damage and be readily accessible. The rationale for Rule 12-518 is to protect cables from mechanical damage when they come within 1.5m of the floor unless protected by location. Given that panelboards are installed in an area not subject to damage, then the non-metallicsheathed cable entering the panelboard would meet the intent of Rule 12-518, not requiring additional mechanical protection.
