Did old knob and tube wiring tend to run hot and neutral wires separately?

Should I plan for potential current capacity demands when sizing a circuit?

7 + 4 = 11 amps. This is never a problem on a 15 amp circuit. Sump pumps are not a continuous load in normal situations. If you treat the pump as a fastened motor for load calculation, it's still ...
