*Since it is going to be a rental unit you should expect the worst from
your tenants. You don't want them running extension cords or blowing
breakers from electric heaters or air conditioners. Put each bedroom's
outlets on a separate 20 amp circuit and make some of them double
duplexes (Quads). You can go the extra mile and install one quad on a
separate 20 amp circuit near a window for an A/C, but the one 20 amp
circuit for all of the outlets will probably suffice with today's energy
efficient air conditioners unless they are very large rooms.

I agree about trying to prevent future problems, especially since now is
the best time to include all of the possible outlets and cirucits that
will achieve that. I usually run a lot more than the minimum required
number of circuits, and I put less than the maximum number of allowable
outlets on each circuit. I also use nothing less than 12 guage wire in
any circuit (no 14 guage anywhere), even though that may be overkill.
And, with the exception of circuits that require 20-amp breakers (such as
kitchens), I use 15-amp circuit breakers even though the 12-guage wire
would allow 20-amp circuit breakers.

Pigtail the receptacles instead of feeding through each device for less
maintenance down the road.



I am not sure what pigtailing the receptacles means. I know about
pigtailing the grounds (which I learned here on this newsgroup), but I am
not sure about what pigtailing the receptacles means.


*You just splice your feed-through wires together and then splice jumpers
onto those to feed your receptacles. That way the full load of the circuit
is not going through the receptacle. This causes the receptacle
terminations to be less affected by heat which can cause loosening of the
termination screws. Also if there is a problem with one receptacle it does
not affect the ones downstream.
