30a needs the 30a plugs like the L6-30R. Do not use regular 20a outlets or fixtures on a 30a branch, they are not designed to handle a load over 20a and if more than 20a is drawn they will not trip if you have them on a 30a breaker. It is clearly a code violation as well as being unsafe. Buy more 30a plugs or put your 20a plugs on a 20a circuit with 12gage.

20 amp receptacles cannot handle the 30 amps.

The difference between the 15 and 20 amp outlets is the slot.

Neither can a .98 cent 15 amp 110v receptacle handle 20 amps. The blade difference prevents you from plugging in a 20 amp load.

They let you put 15 amp

15 amp duplex receptacles are allowed on 20 amp circuits, and can handle a 20 amp load.

When connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in table 210.21(B)(3).....

The minimum receptacle or outlet on a 30 Amp circuit is a 30 Amp receptacle

Can't put a 20 amp receptacle on a 30 amp circuit here either.

Then you have to take box calculations fill into concideration.

And if the receptacle screw can accept a # 10 wire.
