TZT14 Technical data needed

I'm updating my electronics suite on my Hatteras. I'm also completely rewiring the entire 12v system on the boat prior to the electronics upgrade. I'm unable to find specific amperage draw on the complete electronics pkg I will be having installed...

Here is everything that will be installed if there someone who could enlighten me or point in the right direction to find this information it would be greatly appreciated.

1 TZT 14 14" NAVNET TZTOUCH
1 PP 5036 NAVPOD TZT 14
1 DRS 4D 4KW 36NM DIGITAL UHD DOME
1 DFF1 UHD 600/1000WT CHIRP SOUNDER
1 M 265LM 1KW CHIRP IN HULL MED &L FREQ
1 POINT 1 FLUX HEADING GPS MODULE

Thanks in advance

The install manual of each item has a specification page that list power draw. It can also normally be found on the product brochure. Keep in mind that unlike many companies who use nominal power, we calculate worse case. The unit on with all functions used and brill at max and power dropping below 12v (which causes current to go up). Fuses are normally rated about twice of max power draw. Breaker rating should be in-between to pop prior to fuse.
