Motors

Motors takes the horsepower, voltage, conduit type, breaker and fuse type for a three-phase motor, and gives back the full-load current, breaker, fuse, conductor, ground, conduit, starter and overload, with a one-line drawing.

The drawing

The motor branch circuit drawn as a one-line from the panel to the motor, each part numbered and sized with its NEC section.

Drawing the program wrote: 10 hp at 460 V, table FLC 14 A: a 35 A inverse-time breaker, 3 x 14 AWG Cu in 1/2 in EMT at 13% fill, a 14 AWG EGC, a 30 A hp-rated disconnect in sight of the motor, and a NEMA Size 1 starter. The overloads wait for the nameplate FLA.

The example, step by step

The values the tool opens with.

  1. Motors in Stinger Pro: The tool opens on 10 hp at 460 V: FLC 14 A, 35 A inverse-time breaker, 25 A time-delay fuse, 14 AWG Cu, 1/2 in EMT, NEMA 1, overload 16.1 A, with the work beside it.

    STEP 1 OF 4The tool opens on 10 hp at 460 V: FLC 14 A, 35 A inverse-time breaker, 25 A time-delay fuse, 14 AWG Cu, 1/2 in EMT, NEMA 1, overload 16.1 A, with the work beside it.

  2. Motors in Stinger Pro: The one-line: 35 A breaker, 3 x 14 AWG in 1/2 in EMT, 30 A hp-rated disconnect, NEMA Size 1 starter, then the 10 hp motor, with the numbered table below.

    STEP 2 OF 4The one-line: 35 A breaker, 3 x 14 AWG in 1/2 in EMT, 30 A hp-rated disconnect, NEMA Size 1 starter, then the 10 hp motor, with the numbered table below.

  3. Motors in Stinger Pro: The motor tables: full-load current by hp from Table 430.250, and breaker, fuse, starter and heater by hp and voltage.

    STEP 3 OF 4The motor tables: full-load current by hp from Table 430.250, and breaker, fuse, starter and heater by hp and voltage.

  4. Motors in Stinger Pro: The raceway table: wire, ground and conduit by hp and voltage, under the full-load current and protection tables.

    STEP 4 OF 4The raceway table: wire, ground and conduit by hp and voltage, under the full-load current and protection tables.
