How do you add a 240V outlet for a second clothes dryer?

Answer 1

At the service panel (breaker box) you'll need a double-pole breaker rated for the dryer (probably 30 amp) and run two "hot" wires (red & black) using 10/3 w/ground cable. The neutral (white) and ground (bare) are just like standard 120V connections.

Answer 2

for USA, Canada and other countries using standard 60Hz electrical services

You should put in a separate circuit back to the breaker panel.

Don't try to run two dryers from the same circuit because, even if the breakers protecting the circuit don't trip (which they may or may not do, depending on the total current taken if both dryers were operating) the two dryers could easily overload the wiring and it could cause a house fire hazard.

ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING

- BREAKERS, CABLES OR OUTLETS -

ON ANY ELECTRICAL POWER CIRCUITS

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work

AND

always use an electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

Answer 3

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
