Yes - a terminal bar. Ideally it is located in a protected enclosure or shielded so that stray objects cannot touch the screws. There are "bridges" sold for the segmented terminal bars that cross the insulated segment wall to join 2 screws together.
- - Be careful with the use of the word "stranded wire". All approved marine
wire is made of many more individual strands than household stranded wire. This is for flexibility. Bus bars and solid terminal bars are used to connected multiple marine
wires together using ring/loop end terminals.
- - Only SSB
HF applications will use flat copper "ribbon" for RF grounding purposes.
- - Tinned marine strands are preferred over plain marine copper strands to help reduce oxidation/corrosion. Nigel Calders Electrical/mechanical boat book describes it all very well.
