Default Battery cable size

I'm at the point of running wiring from the aft fuselage to firewall (RV10) and am trying to decide what size battery cable to use. Is AWG 02 good or is 01 better? What amp rating should I be looking for?
Also I'd like to use firewall pass thru connectors.
I'd like to use a pass thru connector that can be insulated but having trouble finding one. Source suggestions?
Thank you!
Scott

#2 welding cable, like one of these: https://www.amazon.com/s/ref=nb_sb_n...+welding+cable

Use #6 welding cable for the alternator output.

The RV-14 comes with a nice SS firewall passthrough. Van’s part number is F-00001. http://vansaircraft.com/cgi-bin/stor...&action=search

Use a piece of fire sleeve a few inches long on the inside of the passthrough, then a larger piece of firesleeve on the engine side to go over the wires, then a hose clamp to hold it on the outside diameter of the passthrough.

Thanks Carl!
I actually saw that on Amazon but wasn't sure about it. I'll use that (good price too). Didn't see a picture of that firewall pass-thru on Van's...
Thank you...helps a ton.

Default yep

Second that on the #2 cable.

I ended up buying the tefzel wire up front, so I used it. If I had to do it again, the welding cable would be my choice...it's FAR more flexible than the tefzel wire.

I used welding cable for battery and contactor wiring, works good.

You have to order the F-00001 passthrough using Van’s “the list”.

Thanks Bob,
Bob Nuckolls has a nice description on how to make your own terminals for the connection for cable. May try it.
Thought West Marine had a nice pass thru but can't seem to find it.
Probably get the one from Van's

I wanted one that bolts to the firewall but these look pretty stout..don't look like they'd come loose.

Interestingly that one does not even mention firewall use, unlike the versions from the race care stores.

They label it for "sealing" use.
