Sizing system bonding jumper

[Strathead]

And if I'm looking at the face of it, width x height is not going to tell me how thick it is.

You are being obtuse.

You are being obtuse.

I am.

I was just trying to defend Infinity a little seeing as how if "cross sectional area" isn't mentioned along with simply multiplying width times height, then that suggestion isn't it either.

A door may be 3 feet wide and 84 inches high, but, that doesn't tell me how thick it is.

No offense.

I'm sure they'll get the jumper all worked out.

Semantics. Each of you is picturing the bus in a different orientation.

Cross-section area is a product of the two smaller dimensions.

When discussing a conductor's size, we aren't talking about its length.

But as you wrote previously, T250.102 tells him how to figure the size and your suggestion isn't it. As I stated, bus width times bus height gives the area, then chapter nine tables to find a conductor/s that have the equivalent area. Conductor size is based on the size of the conductors, not the amperage of the overcurrent protection.

This is for a temporary fix so my method is fine but for arguments sake once I have the cross sectional area of the bus where in the NEC will I find the ampacity of that bus?

That's the whole point Larry.
The cross-sectional area must be mentioned somehow.

You can't simply say multiply the width times the height.
