Maintenance Electrician, Residential & Commercial Electrical Contractor
Hello fellow electricians,
I'm in a bit of a situation here, and I'm not sure if I am interpreting this correctly.
I'm currently installing a new 200a service entrance on a local residence. (I'm located very far in eastern Canada)
I've always used a #4 bonding wire going from my panel to my meter base. However, the inspector has come back to me, saying that they have changed their inspection guidelines (Apparently nobody knew this before, until an inspector stumbled across it in the CEC)
They are now saying that because I used aluminum conductors in my service entrance, I have to use a #4 bonding wire from the panel to the meter base, citing Table 16 as the reason for the change. They state that in the table, under "Aluminum AWG or Kcmil", it states #4.
However, I disagree with that interpretation. I have always interpreted those sizes to be dependent on whether then bonding wire's material is either copper or aluminum, and has nothing to do with the service conductor materials... I used copper bonding wire, and installed a #6, and they said it has to be changed.
Am I interpreting this wrong? or is my local Government going even more bananas?
