*Carried over from the "Residential Homerun" Thread* Residential Homerun OK, I'll get the Ball A-rollin'...

System is 208Y/120 VAC 3Ã˜ 4 Wire.

Panelboard has 200 Amp Max. load.

Batman has been captured by the Penguin... oh wait, now it's the other way around... (must add humor).

We have a series of Modular Furniture, which is 40 Feet from the Panelboard (AKA Sub Panel).

The Mod. Furniture of concern has 12 Workstations total - split up into two sections (6 W/S "on the left", 6 W/S "on the right").

We will run two "Full Boats" ("Full Boat = 4 Wire Multiwire Circuit) from the Panelboard to the Mod. Furniture, via a common 1" Raceway (EMT in this case).

One "Full Boat" feeds the 6 W/S "on the left", and the other "Full Boat" feeds the 6 W/S "on the right".

Branch Circuitry per "Full Boat" will consist of 3 # 12 THHN cu for the Ungrounded Conductors, 1 # 10 THHN cu for the Grounded Conductor. To Bond the Raceway, an additional # 12 cu is included for the Equipment Grounding Conductor.

Circuit Breakers in the Panelboard for these Branch Circuits are 20/1 (20 Amp single pole).

Load Current per Line (L-C Loads) will be 12 Amps Max.

THD (Total Harmonic Distortion) is <10%

OK, let me know:

- Is this NEC compliant?
- Will it work?
- Is this a Design Issue?
- Does this example make sense?
- Will the Penguin escape once again?

Feel free to present any information you wish.
