What is the difference between 10 30P and 10 30R?
Older homes and dryers still have the 3-prong NEMA 10-30 plugs and receptacles. These NEMA 10-30P plugs will only work with the 30 Amp 240 Volt NEMA 10-30R outlet, as you know. If you purchase a new dryer or new construction, post-1996, then you will likely run into the 4-prong NEMA 14-30 plugs and receptacles.
What is a 10-30 plug?
NEMA 10-30 is an nongrounded 120/240V device (hot, hot, neutral), NEMA 6-50 is a grounded 240V device (hot, hot, ground). A 10-30 receptacle will be protected by a 30 ampere breaker, and supplied by wires only rated to carry 30 amperes of current. If you plug a 50 ampere load, into a 30 ampere circuit.

How do you wire NEMA 10 50?
Loosen the NEMA 10-50R’s W terminal screw with a slotted screwdriver. A 10-50R usually uses a silver screw on its W terminal. Push the neutral wire under the 10-50R’s W terminal and tighten the screw. In most cases, the neutral wire uses white insulation.
What is the NEMA designation for a common T slot receptacle?
NEMA 6-20R Connector
The NEMA 6-20R (T-Slot) is a 3 Wire grounded connector rated up to 250VAC and 20A. The 6-20P has a horizontal and vertical blade to prevent attachment to lower ampere rated receptacles. However, the 6-20R (receptacle) offers a “T” slot allowing connection of both a 6-20P and a 6-15P.
Are dryers 30 or 50 amps?
