similarly, Can you wire a 4 prong outlet with 3 wires?

In an existing installation (such as an older home built in the 1950s), it is considered Code-compliant for the kitchen range or the clothes dryer to be installed using a 3-wire cord and plug. The 4th wire in that cord and plug configuration is an equipment grounding conductor. …

on the other hand, Does a 3 prong dryer outlet have to be grounded?
