Proper way to wire double receptacle in middle of a run

What is considered the proper way to wire a double receptacle (Two receptacles in a double gang box) that's in the middle of a run?

Do you connect the black wire "coming in" to two pigtails going to the respective brass screws on each receptacle & the black wire continuing out further down the run? Basically four wires tied together. Same for neutral/white wire except connecting to silver screws

or

Do you connect the black wire coming in directly to the brass screw of first receptacle then connect another black wire on the second brass screw on that same receptacle which you then connect to a brass screw of the second receptacle. You then connect another black wire form the second receptacle to "outgoing" black wire that continues down the run - basically more of a "daisy chain" method. Same would apply to white wires via silver screws

Either way is acceptable.

I'm not an electrician, but I question Joed's reply. It's my understanding that pig tails are the proper method. Then if one receptacle or switch becomes inoperative the rest will continue to work. Correct me if I'm wrong.

What if some type of critical appliance is connected down line and one of the receptacles becomes inoperative? If daisy chained then you loose power on all remaining units. The appliance could be something like a refrigerator, an alarm, etc... or possibly some type of medical appliance.

Pigtails are only 'required' for the neutrals of a multi wire circuit.

If the incoming and continuing hot wires happen to be connected directly to one another with a pigtail going to the receptacle then the neutral must be similarly pigtailed.

I'd agree that either method is acceptable and widely used. It's incredibly rare for a receptacle to go bad in a way that disconnects the 'passthrough' capability. And even if it does, it's not a safety issue, only a repair issue.

The two ways I wouldn't do it are:
* By using the push-in connectors on the back of cheap receptacles
* By trying to connect 3 wires to two screws on a receptacle (code violation)

No code requirement for this.

Do you connect the black wire coming in directly to the brass screw of first receptacle then connect another black wire on the second brass screw on that same receptacle which you then connect to a brass screw of the second receptacle.
Either way will work. However, I do not like to rely on the device for my connection so I always pigtail.
