Rewiring s small 650 square foot lake cabin. Will install AFCI protected circuits for the bedroom receptacles. Wondering if the light fixtures controlled switches and smoke alarms need to also be protected. Will install smoke detectors inside each bedroom. Would one detector be sufficient outside as both door are next to one another. Would one 15-amp circuit covering say 8 receptacles, 3-4 smoke alarms, and four light switches to control two ceiling fans and an attached lights not over tax the circuit. Two - a rare maximum of four persons will inhabit this season cottage. Thaks.
