Default Firewall passthrough for battery cable

I would like to know what others have done or thought of doing about the Van's standard plastic grommet through the firewall for the battery cable. It is in a tight spot and probably can't put firesleeve or a steel cover there. Perhaps just some red RTV? Major change in cable routing? Leave as is? Input appreciated.

I just used the stock location and snap bushing, used a high temp sealant over that.

Firestop 2000 http://solutions.3m.com/wps/portal/3...be9CJ1ZTM6FQgl

I used it based on recommendations from a RV buddy------dont know if it is the current choice or not???

Dan Horton may have done some testing on various sealants that may be useful-------try doing a search.

Default Pass Thru

I was not real fond of Van's solution. This is what I ended up using:

I purchased a marine bulkhead pass-through. It's bulky and a bit heavy but I didn't feel comfortable with the snap-bushing. Besides, I like terminating the cable at the bulkhead rather than having it physically pass through the firewall where it could possibly chafe and ground or be severed in an accident and spark a fire. Probably overkill but I felt it was the right way to do it.

Yeah, I ordered a couple of marine pass throughs but they were really bulky. Then I found the VTE product. Compact, easy to install, and carries 550 amps...oh, and they are comparatively inexpensive!

Oh, still have the marine connectors, if you decide to go that way...I will make you a deal!

These are the 400 A version, which has been discontinued.

I have 2 red ones, sorry Black was out of stock everywhere but my intent was to spray one of them Black.

If you want them, send me a message!

Default Pass thrus

Not an RV builder but I use flanged stainless tubing(035 tubing .063 flange). I made my own but they are available from the company that makes the all stainless cabin heat boxes. Flange is tig welded and four 6-32 stainless screws with stainless lock nuts hold it in place. Fire sleeve around the cables, sealed with the 2000 degree "goop" from Lowes.
I made four of these, also use stainless bulkhead fittings for fuel line, brake lines etc.

I used a -8 AN steel bulkhead fitting and with a lathe bored out large enough for slip fit of the cable. Also shortened the fitting to overall about 1.2" long and put decent-size lead-in/lead-out chamfers to keep from chafing the cable. After 8 years in use, the cable looks perfect.

Just remember to push the cable through the bulkhead fitting before crimping on the last end...

For those who have used the VTE bushings, did you buy the Greenlee punch? If no, how did you make the 1.375x1.125 size holes?

Default Punch

Sent you a PM.

Couldn't justify $350= for the punch for only two holes so cut them manually.

Took less than 1 hour for both holes...
