I just acquired a new 6" jointer...the Craftsman which is made by Orion.
It has a (true) 1 HP motor and comes pre-wired for 110, but can be easily
rewired for 220. My questions a

1. What is the advantage of wiring for 220 vs. 110? Different Websites
say different things...some say the motor will run cooler, some say it
will run "better" (not defined!), some say it makes no difference
whatsoever. Opinions?


Makes no difference if line voltage drop were the same.

The difference for 220V is half the conductor size with half the current
draw. In other words with the same conductor size you could run your jointer
at twice the distance with 220V.


2. The 220 drop in my basement is the type with two straight prongs (at
an angle) and one L-shaped. The L-shaped prong carries the neutral.
(It's a 30-amp "dryer outlet.") The jointer's manual says I must connect
the ground wire to a true ground. My question is...if I connect the
ground wire to a neutral instead of a true ground, am I still properly
grounding the tool?


Don't connect the jointer to the 30A circuit. Maximum breaker size 15A as
your motor is only about 8A at 220V. I would not interchange ground with
neutral although the neutral is grounded at the main panel and the motor
should run. Neutral carries current while ground does not except during a
phase to ground short circuit. There should not be a neutral in your 220V
configuration - all you require is two phase conductors and a ground unless
your Craftsman wiring setup dictates otherwise. You need a 2-pole, 3-wire
grounding plug and a matching receptacle type NEMA 6-15 - verify with your
Craftsman instruction manual.




Total newbie here, so any advice would be greatly appreciated.

Thanks in advance,
