For 12v one circuit isnt going to work...

eg standard PCB HBP are 12v 11amp 1.1ohm resistance about 130 watts

maybe 2 ccts in parallel

5 * .52 = 2.6 per cct
in parallel 1/2.6 + 1/2.6 = 1.3 ohms a little high (the PCB HBP already takes to long)

for same as pcb hbp

1.1 ohm..
so 2.2 ohms per cct, ie 2 lengths of 4.23 feet in parallel ( no idea what a .23 of a foot in inches sorry... im metric)
Ie

4.23 * .52 = 2.1996 ohms
in parallel 1/2.1996+1/2.1996 = 1.0998 ohm

which is 12 * 1.0998 = 10.91amps, this is fine on standard ramps type electronics (use a heat sink on the mosfet, or a better mosfet than the standard one)

or you could use 26v at 5amp on your current resistance of 5.2 ohms for 130 watts (standard 11amp (heated build platform) ramps fuse is only good up to 16volts)

hope this scribble is understandable :P
