Were going to install a Hayward HP21104T 5 ton pool heater heat pump. Installation instructions are here;
http://www.hayward-pool.com/pdf/manuals/heatpro 4T installation.pdf.
Specs call for Maximum 60 amp with "Minimum Current Ampacity" of 35 amps. What I have been reading is that wire needs to be sized the Minimum Circuit Ampacity of 35 amps yet maximum (not minimum) "fuse" size of 60 amps
There is an article that describes why here:

Installer said he typically installs with #8 wire with 50 amp breaker. The outdoor supply panel already has an unused 50 amp breaker in it. The whip length needed is only about 10 feet. I'll probably run #6 whip and keep the 50 amp breaker.
What do you all think?
