How wrong is this wiring idea? (lemmy.world)

Can I put an additional load before switches on a dedicated circuit?

The example circuit goes from the service panel to a two-way (SPDT) switch at the house back door. From there the circuit goes to another two-way switch out in the garage. The circuit then powers the garage lights.

The goal is to add additional lights on this circuit near the service panel so that the same switches would also control the new lights.

How wrong would it be to add this new load between the service panel and the first two-way switch? This would save the (huge) effort to run wire from the garage back to the house.

You're essentially asking if you can add a light in series with other lights. Almost all ac lighting is done in parallel, thus the live and neutral at each socket.

Technically it would probably work, but if your light can't handle the full load current of the other lights on the circuit, it'll burn out and then cause those lights to go out as well.

No, they wouldn't burn out, the garage lights would only work when the light near the panel is lit and both lights would be dimmer if lit at the same time.
