ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics 200 amp License limit

Doug, given the history there, common sense does indicate a need for some kind of barrier in that area, even though teck does provide some protection. 6-112 talks about the windows, and refers to conductors relating to the supply authority. As you know, triplex insulation can break down over time, and access would be more of a concern than with teck.

Where Do I start?
Doug explained the levels of Contractors licences in BC so that is coverd for me too. The meter base is a 400 amp 4 position meter base not 2 times 200. The service is therefore a 400 amp service or maybe less if say the load calc showed 260 amps it could be a 260 amp service if smaller conductors were installed subject to the rules for parallel conductors. Regardless no C licenced contractor could work on this house in Victoria or I expect the rest of BC.
BC Hydro will not drop two triplexes to a parallel service like that. The will drop a single 400 amp triplex and terminate the conductors in single 3 barrel lugs. A mast is defined as a maximum of 200 amps and any need for a greater size service will require a certification from a structural engineer or a 6X6 wood mast for the side load of a 400 amp drop. We don't normally approve parrallel masts as meeting the specs for a single mast but on that point I would need to speak to an engineer to decide if it is adequate to the load for a single 400 amp triplex drop.
As for Mechanical protection it always depends on the hazard. Parking blocks might be enough or a bollard. if cars can pull up to the house. Mechanical protection can be required for ridgid steel pipe if there is a hazard of mechanical damage beyond what ridgid pipe would normally be able to continuously withstand. Fuel for the fire.

Thanks

They Ran 2 seperate triplexs one to each Mast I had a closer look today.

Never heard of the up to 200amp thing before? When I wrote my licence there was a guy writing his residential licence. Not sure what voltages or amps he can go up to. (This is in Ontario)
Also, isn't there a rule for mechanical protection in a driveway? I'll look it up when I'm in my truck.
"Here in British Columbia there is 3 classes of contracting tickets
Class C is restricted to 200 amps single phase 300 volts
class B 750 volt 3 phase
Class A no restrictions"

I have my Construction and Maintenance Inter-provincial licence in Ontario. Would I have any restrictions out west?
