These are real pages from the book. The table of contents is the full one: 8 parts and 61 topics.
You're standing at an open terminal box with twelve numbered leads, and the job calls for 277/480. The last tech who wired it isn't around to ask.
The manual gives you a connection table and a few paragraphs: T4 with T7, T5 with T8, T6 with T9… As plain text, the lead numbers stop meaning anything by the third pair.
In the book, the 12-lead page draws the windings as coils: high wye, low wye and delta side by side, each lead number on its own coil and each voltage in a box.
The same goes for wye and high-leg delta, three-phase amps from kVA, 3-pole vs 4-pole transfer switches and the NFPA 110 monthly test. Each one has its own page.
You can see which coils are in series and which are in parallel, and you make the connection without going back to the manual. Then you check it against the manufacturer's diagram for that unit.
One path from fuel to load, the engine, the alternator, electrical math and sizing, transfer switches and controls, codes and testing, troubleshooting flowcharts and a review for the truck: 65 pages, all illustrated.
Think of it this way:
It's the monthly test. The ATS is about to transfer, and the facility manager asks why the generator hasn't picked up the load yet.
The night before, you went over the ATS time delays page: the sequence drawn as a timeline, normal fails, engine start delay, transfer to the generator, retransfer delay, retransfer, then cooldown, each delay in its own box. So you tell him which delay it's in, without guessing.
Same with the fuel system, 12-lead reconnection, kW vs kVA, NFPA 110 Level, Type and Class, and the no-crank flowchart: each one on its own page.
Generator Technician Illustrated is 65 illustrated pages in 8 parts, one topic per page, ending with a formula sheet, a code map and the service visit order, each on one page for the truck.
What you see drawn, you don't have to memorize.
The generator as one path from fuel to load, standby vs prime vs continuous ratings, emergency vs legally required vs optional, NFPA 110 Level, Type and Class, the nameplate, and how RPM and poles set frequency.
The diesel four-stroke cycle, the fuel system from tank to injector, fuel quality and storage, natural gas and LP engines, cooling, lubrication, intake, turbo and exhaust, starting batteries, and isochronous vs droop governors.
How the alternator makes voltage, the brushless excitation path, rotating rectifier diodes, PMG and auxiliary winding, field flashing, the AVR, 12-lead reconnection, phase rotation and megger testing.
kW vs kVA, power factor and the power triangle, wye, delta and high-leg delta, single-phase and three-phase amps worked out step by step, motor starting voltage dip, and harmonics.
How an ATS transfers step by step, its time delays, pickup and dropout, open, closed and delayed transition, 3-pole vs 4-pole and the neutral, service entrance and bypass-isolation switches, controller shutdowns and paralleling.
Lockout/tagout on a generator, arc flash and NFPA 70E, backfeed, CO and fuel hazards, NFPA 110 weekly and monthly tasks, the annual load bank test, the 36-month 4-hour test, ATS testing and wet stacking.
The fault-finding order, then flowcharts for no crank, cranks but won't start, starts then shuts down, no or low voltage, hunting, overheating, and how to read exhaust smoke.
A formula sheet, a code map and the service visit order, each on one page, plus the pairs that get mixed up most often and how to use the exam outline.
At the end of the book: A formula sheet, a code map and the service visit order on one page each, plus troubleshooting flowcharts.
Test yourself with exam-style questions on engines, alternators, transfer switches and sizing, each answer explained with the page where it's drawn.
See the mistakes techs make most often on service calls and load tests, each one drawn wrong and right so you catch it before the customer does.
📄 This is a digital PDF book sent to your email: nothing is printed or shipped.
PDF by email: We email you Generator Technician Illustrated as a PDF, together with the two free books. It's a single payment: no installments, no extra charges.
You get the whole machine as one path from the fuel tank to the load, so the engine side and the electrical side stop feeling like two different trades.
You review one topic per page, map it to the exam outline with the page in part 8, and the mixed-up pairs (kW and kVA, wye and delta, Type and Class) each get their own drawing.
You keep the formula sheet, the code map and the troubleshooting flowcharts printed in the truck, so every call follows the same order.

We refund everything if the file won't open, if the book isn't what you see here, if you were charged twice or if the email doesn't arrive. Just email us.
You pay once. No subscriptions.
Yes. The book follows one path from fuel to load, so an electrician gets the engine side drawn and a mechanic gets the electrical side drawn (wye, delta, kVA, transfer switches), without pages of basics you already know.
It's checked against the editions in force when the book was written: the EGSA Generator Technician Certification exam outline, NFPA 110, NFPA 70 (NEC Articles 250, 445, 700, 701 and 702), NFPA 70E and OSHA 29 CFR 1910.147. Every code reference names its article or section, so you can check it against the edition your state or jurisdiction has adopted. States adopt the NEC at different times.
No. It's an independent study guide. It has no affiliation with or endorsement from EGSA or NFPA, and it doesn't copy text from the codes: everything is explained in our own words and drawings.
No. It's a study and review aid. It doesn't give you a certificate or count toward EGSA certification, and it doesn't replace hands-on training, manufacturer instructions or the supervision required for electrical work.
No. They're written for this book in the style of the exam topics, and each answer points to the page where it's drawn. They aren't official exam questions.
PDF by email, sent to the address you enter at checkout. The 2 bonus books come as PDFs by email too.
No. It's a one-time payment. There's no subscription.
It comes as a PDF by email, not as a printed book. You can print it at home or at a print shop and keep it in the truck.
You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
No more rereading the manual with nothing sticking.
The 12-lead reconnection: you see it drawn, and that's it.
You show up to the exam or the service call knowing where everything is.
Drawings make studying faster.
