A clothing dryer is a electromechanical major appliance, that is used to remove moisture from a clothing load, and after will become dry. Smaller load less time to dry. It is very important how much clothing you put in the washing machine. The more clothing the longer to DRY:) The legs should be leveled.
The installations of electric dryers required a plug in box with the appropriate receptacle for dryers.
The wiring is 3-#10 wires plus ground ( Type NMDT ). The breakers are double 30 amps wired according to the local electrical code.
Before plugging in the dryer, check the outlet for proper electrical connections and connect voltage. The voltage between (triangular hole) black ( L2 ) and (triangular hole) red ( L1 ) is approximately 240 volts ac. The voltage between L1 and (letter L) neutral (white) is 120 volts. The voltage between L2 and (letter L) neutral (white) is 120 volts. The voltage between L1 and (round hole) ground (grin or bare wire) is 120 volts. The voltage between L2 and (round hole) ground (grin or bare wire) is 120 volts.
