Step-by-Step Guide
-
Step 1: Verify the electrical requirements of the dryer.
Most sold for use in the U.S. and Canada require a 240 volt / 30 amp supply. -
Step 2: Check that any existing dryer receptacle has this same rating and note number of slots (either 3 or 4 slots).
, If purchasing a cord set by matching the electrical rating of the receptacle; remembering the slot pattern will not matter, as they are standardized.
Most hardware stores and nearly all home supply centers offer cord sets for electric ranges and dryers with a choice of either 3 or 4 conductors for under $25 or so.
These cord sets may look similar, but are not interchangeable due to different electrical ratings.
Dryer cord sets are 240V/30A and range cord sets are 240V/40A for use in the U.S. & Canada. , The cord set selected should have only 3 wires (line 1, line 2 and neutral; no ground wire).
The center wire of this cable is the neutral wire and the outer wires are the "hot" line 1 and line 2 wires.
These hot wires connect to the outer 2 connections the power terminal block of the dryer, does not matter which is which as long as one hot is connected to each of the outer terminal connectors. , Since in this case the neutral serves as a neutral and a ground connection, a jumper conductor (ground strap) is also connected to the center terminal and to the frame of the dryer.
A green wire could also be used to connect the center connector to the frame of the dryer. , If the dryer cord does have colored wires, white is the neutral wire to the center connector, the red and black wires are the hot line 1 and line 2 wires which connect to the 2 outer connections of the dryer terminal block.
Don't forget the ground strap or green wire jumper from the center connector to the dryer frame. -
Step 3: Obtain a cord set with the same electrical rating and number of slots as the receptacle.
-
Step 4: Connect the cord set to the terminal block at the rear of the dryer.
-
Step 5: Notice that the center wire (neutral wire) of the cord set goes to the center connector.
-
Step 6: Understand color coding of conductors in the cord set.
