take the wattage and divide by 100

or take the wattage

multiply by .7 for efficiency

divide that by 12

that number is how many Amps it pulls

Zed lists the size fuse you need for the given ohm load in his manual for the new amplifiers...

Heres the draconia part from the manual....

Fuse rating for 4 ohm load - - - 25A-30A depending on usage

Fuse rating for 2 ohm load **** - - - 30A-50A depending on usage

**** under normal operating conditions the fuse rating for 4ohm loads will suffice for 2 ohm loads. If the amplifer is driven for long periods of time into 2 ohm loads the fuse rating may be increased as shown. DO NOT OVER FUSE ANY AMPLIFER

Also here is the link to the new manual... 2011 ZED Manual

Hope This helps

I would say : divide by 10.

1500 watts rms .....................150 A for example !

Am I wrong ?

Yes it does thanks for the reply.

You are welcome.

ZED also tells you how to calculate the fuse rating as well I think it is page 13.... Example: A 100 x 4 at 4 ohms amplifier. We will assume that we will be playing it so musical peaks reach 100w/ch. Ok so 100 x 4 = 400. Divide by .03 = 1333 divide by 5 = 266 and divide this by 12 = 22 amps. Use a 25 or 30 amps fuse.

I have used this with my esx amps and have not blown a fuse yet.
