ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics Can I use a transformer ground as a bond?

I have been stewing over an answer to this
First see rule 10-206 (2) and the only transformer you can ground using the bonding conductor is 1000va or less.
Not a very big store at 8.3 amps.
Second the bonding conductor probably has a lot of splices.
A ground conductor must be continuous (use thermit welding or listed Hypress connectors.
Is the store fed via EMT, ACWU, Short section of PVC and EMT? Maybe the bonding conductor in that pipe is a ground and not a bonding conductor.
We have a mall where the distribution is 600 volts and every store has a transformer for the 120/208 volt requirements. The ground runs as a ring and is located in the dropped ceilings each transformer just taps off the 3/0 ground ring.
In this case a bonding method, either the wire in the pipe or the pipe itself makes the bonding done and add a ground that may take just about any route to the ground electrode as long as it is direct (IE don't go east to get to the west)
The transformer secondary is a new service and the grounding must be done as for a new service. Direct to the New neutral and terminated at the transformer or service entry Switch or combo panel.
The only time a bonding conductor may be used to ground anything is as I said in opening.
