How many electrical outlets can you daisy chain?
So there is no limit to the number of receptacles that can be connected to a home circuit using 14–2 wire, but there is a practical limit to how much load you can put on it. Exceed the rated load and your safety device (circuit breaker most often) which is in series with the wire will (should?)
Are double outlets in series or parallel?
But, in fact, all household receptacles are always wired in parallel, and never in series. In a series circuit, current must pass through a load at each device.
