breaker/wire info/heat pump

[Smart $]

Thanks for the suggestions.
if i change out the fuses on the main ac side(currently 60s also) ,not the 2 for the heat side, over to the 40s -that the 3 ton calls for will that pop them if its a 5 ton?-there for telling me its a 5..

here are the specs the unit pulls if 5 ton

min circuit ampacity 43.4

max overcurrent protection 70

total unit amps 36.6


-any info is appreciated

The AC side would likely pop non-time delay 40A fuses if it's a 5 ton unit... perhaps even time delay 40A fuses. As mentioned earlier, you may want to use time delay 60A fuses for the 5 ton unit.
