Hi, I'm a newly trained electrical contractor in Sacramento, CA.
I have lots of questions so here's one:

How many outlet's should I put on one circuit?
I know there's an 1800 watts (120V X 15A) capacity on each circuit but should I calculate the appliances that's going to be used on those circuits up to ALL 1800 watts??

Marxlaws - it's that way with everything, especially as we get older. The more I learn the more I forget. I have what I call my "contractors bible" it is my cheat sheets for all kinds of stuff, anything I need to reference I add to it. A sample from my electrical sheet -

Outlets—outlet every 12 feet around the perimeter of each room (except bathroom). Codes require that a 6 foot cord running along a wall will be able to reach an outlet from any point on that wall. Outlet required on any wall longer than 2 ft and any hallway longer than 10 ft. No rule as to how high the outlet must be off the floor, but any outlet higher than 46 doesn’t count for the 12ft rule.

Bathroom—Codes require only one outlet in a bathroom., but it must be a GFCI within 3 feet of the sink on a separate 12/2 wire home run to panel. Lights and fan can tie into another circuit.

Circuit load—in general 10 devices on a 14 gauge circuit, 12 devices on a 12 gauge circuit.

Wire staples—within 8 inches of plastic boxes and every 4 ft along a run, unless the wire is running through studs. If wire comes within 1 1/4 in of the edge of a stud it must have a metal plate to protect it.

Smoke detectors—one in every bedroom, one at the bottom of stairs.

Inspections: rough - grounds connected in all boxes, can lights installed and lit up. Final - all connections, covers on. Call building dept @8:00am day of inspection for inspection 2 hour time window.

I have to do this for everything.
Thanks, Jbfan, I think that is supposed to read "at least one outlet" would that make more sense?
Paul, most of the stuff has tons of pictures so I can't cut and paste it here, but here is some stuff for framing. I actually now have a spread sheet I made that if I enter the wall height and the footprint lengths of the walls iit will spit out a cut list of studs, plates, tapcons, nails, insulation, drywall ect... It even calculates using different length plates and such and the cost or savings involved.

Base plates—measure foot print of all walls to be framed multiply by 2 for normal walls and 3 for floating walls. Bottom plate must be ACQ.

Studs— 1 for every linear foot of base plates + 15%.

Fasteners— - concrete fasteners 1 per every 2 linear feet of wall.
- 10 lbs 12d nails for every 100 linear feet of wall.
- 5 lbs 8d nails for every 100 linear feet of wall.

Sofits—5ft of 2x4 for every 2 linear feet of sofit.
1 1 4x8 sheet of 7/16 OSB for every 32 linear feet of sofit.

Doors— stand in the door frame with your back to the hinges, the door swinging in the direction of your right hand is a right handed door, swinging towards your left hand is a left swinging door.

and here is something I use for concrete flat work

Build forms, level, re-enforce sides with stakes so boards don’t move with weight of concrete.
Rebar or wire mesh– secure in place metal edging spikes, get rebar or mesh in middle of slab not resting on bottom.
Release agent—oil wood for easy release.

Screed concrete to level with forms
Float with magnesium bull float
Let sit till water stops coming to surface and water on surface evaporates.
Contraction joints—multiply thickness x 2.5 (4 inches thick x 2.5 = 10ft max distance between joists)
Work surface with magnesium trowel (if water raises to surface, wait)
Work surface with steel trowel
Wet concrete and cover with plastic, keep wet for 3-7 days.

Wood for forms
Wood for screed
Stakes to stabilize form
Plastic to cover and keep wet
Rebar or mesh
Hold down (lawn edge spikes)
Wire for rebar
Oil for form release
Magnesium bull float
Magnesium trowel
Steel trowel

I've been putting together equipment lists for types of jobs so I can make sure I have everything I need to complete certain work. That has been a big help. I store them on my computer and just print them out, they are in check list format so I can check off the equipment as it goes into the truck.
I hate to sound like an ass, since we have a few too many here all of a sudden, but he might have electicuted himself already.
