In addition to a main distribution board, have just fitted this 4 way blue sea switch set that has a positive feed buzz bar and individual blade type fuses for each switch.

http://www.bluesea.com/

This insures that each electrical item is protected by the correct fuse rating. I have also installed a heavy in-line master fuse next to the main battery switch. After taking advice from this forum, all my electrical installations have used Blue Sea components.

IP66 does not equal fully waterproof, should be IP68, or more Des

IP codes
Degrees of Protection provided by enclosures.
An IP number is often used when specifying the environmental protection afforded by enclosures around electronic equipment. These ratings refer to specific tests. The IP number is made up of two components as follows: IP44 The first number refers to the protection against solid objects and the second against liquids. The higher the number the better the protection. see below for a summary.

IP Protection Number Summary

FIRST NUMBER

0 No protection
1 Protected against solid objects up to 50mm eg accidental touch by hands
2 Protected against solid objects up to 12mm eg fingers
3 Protected against solid objects up to 2.5mm (tools and wires)
4 Protected against solid objects up to 1mm (small tools and wires)
5 Protected against dust, limited ingress (no harmful deposit)
6 Totally protected against dust

SECOND NUMBER
0 No protection
1 Protection against vertically falling drops of water eg condensation
2 Protection against direct sprays of water up to 15 degrees from vertical
3 Protection against direct sprays of water up to 60 degrees from vertical
4 Protection against water sprayed from all directions - limited ingress permitted
5 Protected against low pressure jets of water from all directions - limited ingress permitted
6 Protected against low pressure jets of water (use on shipdeck)- limited ingress permitted
7 Protected against the effect of immersion between 15cm and 1m
8 Protected against long periods of immersion under pressure
Note that there is a third number which is commonly omitted which refers to protection against mechanical impacts.

..ah.. the speed of the edit has defeated the mighty Des..... .. I like the definition of "1".. Protection against large foreign bodies .. presumably that means if I tool up with "IP 1"... the Yanks can't invade my boat..... sorry.. childish, I know.. it just amused me....

IP00 is an interesting one which could be applied to lettuce and IP21 which could be a applied to a cocktail umbrella Des
