48V DC bus bars for use on 72V system - is it ok?

[brownj24]

I am trying to find a pair of bus bars to connect to my 72v battery +/- leads.
My battery is 20s28p (72v with max continuous current draw of 80 amps).

It seems everything I can find is rated to max 48V for DC. I assume just for safety around arcing?

Can I still use something like the below product for my application? What are the risks involved, if any (the bus bars will be space apart several inches with plastic cover installed)?

I'm using the exact same thing for 100v DC, you'll be fine.

Bus bars are rated for current, not voltage. As long as the distance between them will hold back the voltage between them, only current matters.

That one should work fine.

This seems to be a common theme I find when shopping electronics ratings. Can anyone smarter than me explain why voltage ratings for a lot of these components aren't even really over 48v?

Possibly it may be due to the fact that equipment operating above 50V requires arc flash evaluation per OSHA standards. Adding the insulation and spacing you mentioned eliminates any issues. Requirements go way up above 600V.

Thanks for the reassuring responses. Much appreciated.
