Give it the system, the occupancy, the calculated load, the service device and the conductors. It gives the service conductors per set, whether the device is allowed on them, GFPE, the main and supply-side bonding jumpers and the GEC, each with its 2023 NEC section, drawn on one one-line and written as a PDF.
The app’s own example, every screen in order, 9 steps.
STEP 1 OF 9The example opens filled in: a 1200 A, 480Y/277 V service, with the answer pinned at the foot of the screen.
STEP 2 OF 9The service: 480Y/277 V, not a dwelling, 960 A calculated load on a 1200 A device, one disconnect.
STEP 3 OF 9The conductors: copper, 75 C terminals, 4 in parallel. The answer: 4 sets of 350 kcmil Cu, GFPE required.
STEP 4 OF 9How it was worked out: the service conductors, 4 x 310 A = 1,240 A at 75 C, then the protection rules.
STEP 5 OF 9Over 800 A, no next size up. Then the disconnects, the GFPE rule for 1000 A or more, and the bonding.
STEP 6 OF 9Combined area 1,400 kcmil and the field marking rule, then the drawing of the 1200 A service starts.
STEP 7 OF 9The one-line: 4 sets of 350 kcmil, GFPE required, MBJ 4/0, GEC 3/0, the field marking and what people get wrong.
STEP 8 OF 9The report: save or share the PDF, or save the job.
STEP 9 OF 9The PDF, page 1: the inputs, the answer and the one-line drawing.
The same 9 screens with the captions burned in. No sound.
MP4, 1.2 MB, 10 seconds.
The PDF report for the same job, all 2 pages as the app writes it.
