Anyhoo, all i need to really do is work out the fuse ratings, and if to
fuse
all pos terminals, or just the paralell ones, and i really want a remote
indicator to show a blown fuse.

Maybe I've missed it, but to have any idea of what fuse to spec we'd
need to know what your maximum currents are for how long, eg 1kW for 1
minute and 200w continuous. Then you simply look at a fuse chart to
see which fuse rating is the lowest that wont blow with those loads.
As Fredxx pointed out, you can get fancy fuses with much tidier specs
than wire fuses, the latter have a pretty big overcurrent margin, ie a
big gap between rated current and will blow current. As far as
specifying fuses go, I think you can forget about startup surges, the
fuses you're looking at will have plenty of thermal inertia.

okay,

1500 watts (centeral vac system) for 5 minutes,

1200 watts (hairdryer) for however long it takes a woman to dry her hair, 10
mins, 15 mins, 3 hours??

900 watts (microwave, that is the input power, cookin power is 550 watts)
for say 10 mins

300 watts (washing machine) i guess for a 2 or 3 minute spin a couple of
times per wash, if it cant get the load balanced then it'll fanny about
rotating the drum left and right at varying speeds for about 10 mins before
giving up,

50 watts (12 inch fan) for a fair few hours in summer,

fuse each terminal at 125 amps with littlefuse mega fuses?

for remote warning of a popped fuse, leds with appropriate resistors accross
the fuses? or something more fancy.
