The tool takes the system, occupancy, calculated load, service device and conductor choices. It gives the service conductors, disconnect, GFPE, bonding jumpers and GEC, each with its 2023 NEC section, and draws the service.
The drawing the Suite made for a 1200 A, 480Y/277 V service: the five answers numbered beside the equipment, then the field marking and what people get wrong.
The report the Suite wrote for this example: every input, how each answer was worked out with its NEC section, then the drawing.
Page 1: inputs and how each answer was worked out for service conductors, protection, disconnects, GFPE, bonding and grounding, and field marking. Page 2: the drawing.
The phone app’s example job, Example - 1200 A service, opened with Open phone job… and worked out by the Suite.
STEP 1 OF 5The example in, before it is worked out: 480Y/277 V, not a dwelling, 960 A load, 1200 A device, one disconnect, copper at 75 °C, 4 in parallel.
STEP 2 OF 5Work it out: 4 sets of 350 kcmil Cu (1,240 A), GFPE required, MBJ 4/0 AWG Cu, GEC 3/0 AWG Cu, SSBJ 2 AWG Cu in each raceway. How it was worked out starts below.
STEP 3 OF 5How it was worked out: service conductors, protection, disconnects, GFPE, bonding and grounding, and field marking, each with its NEC section.
STEP 4 OF 5The drawing begins: utility, meter and 1200 A service equipment with its GFPE sensor, with the service conductors, disconnect, GFPE and main bonding jumper numbered beside it.
STEP 5 OF 5The whole drawing: the five answers, GEC 3/0 AWG Cu, the field marking note and the “What people get wrong” box.
