Field Trainers
Five interactive trainers built by our field team for apprentices, instructors and anyone getting ready for an inspection — conduit bending, a 480V disconnect in 3D, bonding jumper sizing, grounding electrode conductor sizing and three-phase transformer wiring. Free, no sign-up, nothing stored.
Five Trainers
Pick a trainer
Each one opens on its own page with what you will practice, the 2023 NEC sections behind it, the mistakes it is built to catch, and a note on running it in a class. They are the same trainers our how-to guides embed, framed full-width. Suggested session lengths are ours — take longer.
Conduit Bending Trainer: Bend Bench →
Bender marks, take-up, multipliers and shrink for every common EMT bend, with a 3D model of the finished piece and a running degree budget for the run.
Open the trainer Safety switch · interactive 3D480V Disconnect Wiring Trainer (3D) →
The install order on a three-phase fusible disconnect — mounting, raceways, line on top, EGC, load out the bottom, lockout — with the motor and HVAC disconnect rules beside each step.
Open the trainer Grounding & bonding · quizBonding Jumper Sizing Trainer →
Which side of the first overcurrent device you are on, and therefore which table sizes the jumper: Table 250.102(C)(1) on the supply side, Table 250.122 on the load side.
Open the trainer Grounding · scenarios with hintsGrounding Electrode Conductor Sizing Trainer →
What enters Table 250.66 (conductor area, paralleled sets summed — never the amperage), which cap applies to which electrode, and which splices, sleeves and clamps are permitted on the conductor.
Open the trainer 480V delta to 208Y/120V · animatedThree-Phase Transformer Wiring Trainer →
The connection sequence on a delta–wye transformer and the three conductors that land on X0: the neutral, the system bonding jumper, and the grounding electrode conductor of a separately derived system.

Calculators that pair with them
The trainers teach the method; these give you the number on a real job. Every one carries a “Send this to an estimator” button when you would rather have us price the work.

The guides behind them
Each trainer grew out of a step-by-step field guide. Read the guide, run the trainer, then take the calculator to the job. All of the guides are on the field guides page.
- How to Bend EMT Conduit — the guide behind the conduit bending trainer
- How to Wire a 480V Disconnect — the guide behind the 480V disconnect trainer
- How to Size a Bonding Jumper — the guide behind the bonding jumper trainer
- How to Size a Grounding Electrode Conductor — the guide behind the grounding electrode conductor trainer

Learn it here, do it with us
Arizona Electrical Solutions trains apprentices on exactly this work — services, grounding and bonding, transformers, conduit — on commercial projects across Arizona. If you are planning the work itself rather than learning it, send us the job.
