How to Wire Light Switch
I am trying to connect a TP-Llink smart light switch. the existing switch only has two black wires connected to it, which I assume are the line and load wire. the new switch has 4 wires, which all need to be connected – line, load, neutral and ground. pretty straight forward, or so I thought.
I pulled all of the wires out of the switch box to locate the neutral and ground wires and found a bundle of ground wires and another bundle of neutral wires clamped together (please see photo). In my limited experience, I have never seen this before. Would I be able to separate one ground and one neutral wire and connect them to the switch?
This electrical wiring question came from Jeff in Honolulu, Hawaii.
Thanks for your electrical wiring question Jeff.

This electrical wiring project is about wiring a smart light switch in the garage of a old house.
Light Switch How to Wire
From what you have described, and looking at the photo, the home wiring has been installed and crimp connectors have been used for the spliced connections, and this is typical for many older homes.
Here’s what I typically do in a situation like this: Turn off the circuit power. An additional wire may be added to the group of ground wires as they are now, just trim the ends of the wires evenly and add one more wire, then twist the group together and install a twist on wire connector.
The group of neutrals will either have to have the crimp connector removed, or the group of wires may be cut just below the crimp, then strip back the insulation, add an additional white wire, twist together, and install a twist on connector. This will provide you with all the wires you need, including the switch wires, to wire up the TP-Link Smart Switch
