One of the old electrical sockets needed to replaced. It was a Slater brand, with only the option to push-in wires at the back with no screws for hot/neutrals and only one screw for ground. Both the top and bottom plugs were switched off by the same circuit breaker.
I noticed there were two sets of wires coming into the outlet box (one set of black, white and ground; another set of black, white and ground, with the two grounds tied together). Both sets were connected to the outlet (not pigtailed). After disconnecting the wires, I used my multimeter to check across the two Hots on the old outlet, it read 0.0 Ohm and it also read 0.0 Ohm across the two Neutrals.
I installed a new outlet in which I used screws to connect the wires (as opposed to the push-in). I left the connecting tab between the two plugs as is. I switched on the circuit breaker and things appear to be working just fine.
I read through posts related to this on this forum and elsewhere but it isn't clear to me if there is any potential issue with this config.
I understand that leaving the tab in place is the same as what was before. But, is this the right thing to do? Could you please comment?
