Can't find any busbars with ratings over 48v

[Travis55]

I bought these busbars awhile back before doing more research since they were on sale, but I'm noticing now they say max 48V:

I see the blue-sea one has similar specs (max 48v). After googling for over an hour I can't find any that show they are rated for higher than 48v. I know in a 48v system the voltage can spike higher than 48 volts.

Can any suggest busbars rated higher than 48v? Or is this a non issue?

Honestly id be more concerned about the amp rating than the voltage.

So here’s my issue with putting a voltage rating on a hunk of metal, plastic, and hardware:

All that really matters is that the insulation can withstand the voltage without arcing.
I seriously doubt a 48v-rated busbar will fail at 56v, or even 70v.

But if you want to do it by the book, get the expensive victron busbars rated 70v.

Yes, get the biggest amperage rating you can find in a convenient size, preferably double the current you expect.
It will keep the heat down at higher current levels.
