Question 2 -17 Oct -------- There are no dumb questions--until now! If the furnace draws 8 amps and there is a 0.2v drop when it is on, and you change the positive wire to the furnace to a fatt...

The question on how much power (Amps) the furnace will draw is actually rather complex.. But in general I suspect the higher the voltage the greater the amps but it's not a 1:1 relationship also the faster the blower will blow which might result in greater comfort. But you cited a 0.2 volt drop.. NOT WORTH the cost of the wire to upgrade it for 0.2 volts. for 2 volts yes but 0.2 no.
