A complete wiring set up will include: -
1) Main positive and negative supply leads (
pos lead protected by a circuit breaker or heavy duty fuse).
2) A positive bus - a terminal block connecting the main positive lead from the battery, and all of the individual device leads connect to.
3) A negative bus
4) Fuses or circuit breakers
5) Switches
Circuit breaker panels are good way to go - as Tagit says they combine circuit protection and switching. Also .... if you daisy chain wire the CB panel with suitable gauge cable you eliminate a positive bus too. You will still need a negative bus.
Alternately you can buy fuse blocks from Narva or from Blue Seas that have the positive and negative buses built in.
I use Narva's 54450 fuse box

I've noticed that Narva have started supplying a rocker switch panel that comes with either an in-built fuse block or in-built push button circuit breakers. I haven't tried them.
