- First of all, the 1.5 hp would equate to about 10 amps at 110 volts,
- so the situation isn't quite as bad as you think. Second, the size of
- the fuse or circuit breaker is (or should be) related to the size of
- the wiring from the main bus to the device - that is, don't change a
- 15 amp fuse to something larger.
-
- Now, if the saw came with a standard plug for a 110 volt receptacle,
- and the branch circuit isn't loaded with toasters, irons, or the like,
- you can safely plug in your TS. The reason for moving to 220v is that
- it cuts the current in half, so your wiring from panel box to outlet
- can be longer, there is less voltage drop in the wiring, and the motor
- will run better under heavy load. You're also less likely to trip a
- circuit breaker or blow a fuse under some kind of surge-like load (a
- knot or something).
-
- If you want to hook up to 220v, the best way is to run a separate
- branch circuit just for the saw. If you have enough blanks in the
- panel, it's simple enough but should be done by someone who knows what
- they're doing. With fuses it's a little more trouble as you probably
- have to add a separate fuse box. You can indeed hook an outlet for
- 220v from the dryer circuit, although this would be frowned upon by
- most inspectors. You certainly wouldn't want the dryer turned on while
- the saw was running, but if you multiplex the operations it will work.
-
- What I'd do is try running off 110v and see if your saw operates
- smoothly without loading (slowing down) for the kinds of wood you will
- be cutting. If so, stay with it.
