Can I use a hose clamp to ground a wire to EMT?

To give a bit on insight, electrical connections are degraded by oxidation of the conductors. If two bare metal conductors have a good, low-resistance connection at first, the resistance between the ...

not sure why this ground wire keeps tripping the breaker

This diagram makes no sense as drawn. It is not clear how much of that is limitations in the drawing software vs. misunderstanding how 3-way switches are wired. Among other problems, I see: screws not ...

Why do electrical fixtures with multiple live/neutral terminals have only one earth terminal?

Ground must be kept connected. Removing one device/receptacle/light/switch from a circuit must not disconnect the ground path. With two screws you might have ground in and ground out. The next idiot ...

Do I need to ground the junction box for a security light/camera?

Yes, ground the junction box. Connect the Romex ground to the box and pigtail it to the light/camera. Use a multimeter to ensure 120V between hot and ground, and 0V between neutral and ground.

Why do electrical fixtures with multiple live/neutral terminals have only one earth terminal?

Rule #1: Manufacturers never include anything extra The second set of hot and neutral screws is not for convenient daisy-chaining. Yes, they are commonly used that way, but that is not the reason they ...
