## Re: how many outlets and lights

Howdy consider having an electrician come and bid the job. Did you pull a permit? I ask as its getting harder to ever sell a home without permitted improvements. Consider getting a books on basic wiring. Good workmanship and code mandates proper spacing and sizing of the lighting,outlets, wire, fasteners, boxes, GFRI recepticles ... a whole host of items to ensure safe construction.

True but I always use the number eight as a cut off point. Once again no exact reason why using that number.

There is no real code restrictions on length of run or allowable voltage drop.
I would suggest however that you run 12 ga (20 amp circuit) rather than 14ga for the outlets and have that separate from the lighting circuits. That way if you pop a breaker you won't be completely in the dark.

Oh, yes their is a NEC code about voltage drop. No more than 3% on branch circuits and no more than 5% on service and branch circuits.

As a rule. No more than 10 outlets on a circuit. Far as #14 AWG. Use #12. #14 is just control wire. You'll never see a union electrician use #14.

Actually there is not an NEC code, there is onlt a FPN (fine print note) An FPN is not a code requirement.

Very few non-union as well

union does does not denote quality it denotes unity

## Re: how many outlets and lights

Jack is 100% correct on the voltage drop issue...... As a union electrician I pulled miles of #14 in residential applications.

We just stuck to a rule of 8 receptacles on a 15 amp circuit and 10 on a 20. Pretty simple in that 180va is allowed for each receptacle either way.
