[DARARepeater] PowerPole connectors

[Jack Gerbs]

He is correct for building / distribution. wireing. Power poles are internal or wire to wire connections Vs power distribution. Big difference!  Call me if you want more details.

Subject: [DARARepeater] PowerPole connectors

In a recent discussion with a new ham about PowerPole connectors the question of how they claim up to "55 amps per pole."

The other ham in the discussion is a retired electrician and recalls that you need wire larger than 10 AWG to carry 55 amps.

page 20 of the manufacturers catalog...
https://www.andersonpower.com/content/dam/app/ecommerce/product-pdfs/CAT-PPMP.pdf

states....
     "PP15-45 series are the smallest Powerpole(r) housings. They can be used for wire-to-wire or wireto-board applications. Wire sizes from #20 AWG (0.75 mm^2) to #10 (6 mm^2) offer power capabilities up to 55 amps per pole."

several different "Ampacity charts" like this one...

https://www.usawire-cable.com/pdf/nec-ampacities.pdf

state that 10 AWG gauge wire is only good for (at 90 degree temp rise) 40 amps of current.  And the ** at the bottom of the PDF talks about limiting 10 gauge to 30 except in extreme conditions.

Can anybody explain Andersons claim of "55 amps per pole"

Thanks

Steve
