Grounding Requirements for Secondary Distribution Boxes in Canada

Rule 10-000 the Scope outlines requirements for: Grounding of Solidly grounded systems, Impedance grounded systems, and Ungrounded systems. When it comes to electrical standards in Canada, the Canadian Electrical Code is essential. Rule 10-210 requires the grounding connection of the supply authority system grounded conductor (neutral) to be made at one point only at the consumer's service and have no other connection to metal parts of the electrical equipment on the supply or load side from where the grounding connection is. Although Section 10 of the Canadian Electrical Code, Part I (CE Code), which applies to grounding and bonding, has been re-written in the 2018 edition of the Code, I keep receiving questions from the readers regarding the fundamentals of grounding and bonding.
