6. What Is the Difference Between Marine Electrical Cable and Regular Automotive Cable?

Being tinned makes marines wire more corrosion-resistant as compared to regular automotive wires.

Marine cable is larger than regular automotive cable at the same size.

This means a 6 AWG marine cable contains more copper than a 6 AWG automotive cable.

More copper results in a better current carrying capacity of the cable.

Marine cable also carries a durable PVC jacket.

The copper strands in marine grade wires are thinner than the automotive cable, which makes the marine grade wire more flexible.

The video below shows the difference between the two cables.

Watch it for a better understanding.

7. What Is the Difference Between Tinned and Bare Copper Marine Electrical Cables?

Bare copper wires are fairly resistant to corrosion, but tinned copper wires prevent accelerated corrosion against wet and contaminated environments.

In terms of conductivity, bare copper wire is as conductive as tinned copper wire.

A tinned copper wire lasts 10 times longer than a bare copper wire.

Tinned copper wires are comparatively easy to solder, as solder is primarily made of tin.
