Sealing deck for duplex 10ga

[F51]

I need to bring an Ancor or Berkshire flat duplex #10 cable thru the deck as part of my solar install. I have used cable clams on round wires lsuch as coax, but have never had to bring a flat duplex cable thru the deck before. Will the buna n rubber in a cable clam form a watertight seal around duplex cable? If not what should I do?

F51,
I have used Blue Seas Cable Clams to great success....
You simply cut or drill the approx. size and shape of the opening you need in the "rubber plug"....

Choose the size you need for application...
Clam - Blue Sea Systems


Although my solar wiring had a round outer jacket, here is a photo of my two Blue Seas cable clams....been working great for 6+ years and 12,000+ offshore miles (including two Atlantic crossings, etc...)

Fair winds and good luck...

In the US there are tons of rubber grommets that fit Romex (which has pretty much the same shape/size as your duplex cable). I took one of those from a landlubber fitting and put it together with my marine bits to make a fitting that worked quite nicely.

Why not use round tinned duplex marine wire? It's available and IMHO makes a neater/cleaner install than flat wire.

Do you have a part number? I could not find anything larger than instrument wire in round cable.

Simply drill two holes of the diameter of the flat duplex, side by side in the rubber seal of the Cable Clam, to the width of the duplex. You will get a water tight seal. If you can get three holes, side by side, so much the better. I use a lot of Cable Clam seals, they're great!
