I have the Blue Sea's 8 gang panel 8261
I would suggest that you buy a 8271 panel. This one has circuit breakers in it. It was not available when I bought my panel. The 8271 has only been out about a year.
Of corse they make them in lesser switched panel's too.
As to your imedeate question. you need to add up all the amp's of all the curcuit's that your going to run off the panel. Then jump it up maybe 20 more amp's to make way for any additional stuff that you may want to add latter.
Then install a Blue Seas Surface mount breaker beside the Master switch [ON/OFF/1/2] depending on how much amperage your going to push thru this curcuit breaker? A 8ga,6ga or 4ga cable will jump from the master switch out to the breaker and then foward to the console.
