Give me a parameter that is missing, if you would-- the type of load?
...parallel or series with the wires.
...parallel or series with the circuit breaker.
...parallel or series with the utility service.
etc. As I said, If I asked you right here, how far away is San Francisco, you can give an answer, but it will not be the only answer. Unless I tell you exactly where to start at, you can't give a sure answer. Parallel or series, is a relationship question. It requires a reference entity. The load is series to the wires, series to the breaker, but parallel to other loads from the panel, parallel from other panel on the same service, etc.
