      I’m looking for the code that gives the distances of clearance required around and in front of an electrical panel. I don’t see it in the OFC and can’t seem to find it in the OBC. Do we need to refer to the EBC?
      Thanks

      Hi Julien.

      Hope this helps:

      The Ontario Electrical Code:

      Rule 2-308 Working space around electrical equipment
      (1) A minimum working space of 1 m with secure footing shall be provided and maintained about electrical
      equipment such as switchboards, panelboards, control panels, and motor control centres that are enclosed
      in metal, except that working space is not required behind such equipment where there are no renewable
      parts such as fuses or switches on the back and where all connections are accessible from locations other
      than the back.

      (2) The space referred to in Subrule (1) shall be in addition to the space required for the operation of drawout-
      type equipment in either the connected, test, or fully disconnected position and shall be sufficient for
      the opening of enclosure doors and hinged panels to at least 90°.

      (3) Working space with secure footing not less than that specified in Table 56 shall be provided and maintained
      around electrical equipment such as switchboards, control panels, and motor control centres having
      exposed live parts.

      (4) The minimum headroom of working spaces around switchboards or motor control centres where bare live
      parts are exposed at any time shall be 2.2 m.

      you wont find it in the OFC. id be more looking at 2.4.1.1. accumulation of combustible materials. first the room has to be designed to store items other than having electrical equipment in there. and secondly, if the items in the room pose a fire hazard then you can have them removed.
