Operating and maintaining boilers, steam systems, and refrigeration machinery in Philadelphia is a serious responsibility. The Engineer Grade A credential is designed for professionals working with steam boiler, stationary, and refrigeration equipment—where safe operation, accurate troubleshooting, and strong code-aligned practices are part of daily work.
The ICC 314_PA_PH exam is an open-book, time-managed test that evaluates the knowledge you’ll rely on in real facilities: boiler operations, combustion, water treatment, auxiliaries, controls, electrical fundamentals, hydronic and condensate systems, and refrigeration fundamentals. This Exam Book Package gathers the key references commonly used to prepare for the Grade A exam so you can study the way the test is written—by understanding concepts and quickly finding the supporting information when questions get specific.
Instead of trying to memorize hundreds of pages, successful candidates build two skills:
This package is built for focused prep. You’ll be working with materials that cover high-pressure and low-pressure boilers, steam plant operations, refrigeration fundamentals, motor control basics, and the calculations and troubleshooting logic that show up on exam day.
The ICC Philadelphia Contractor/Trades bulletin also provides a content outline for the Grade A exam. Use this breakdown to prioritize your study time and avoid over-studying low-weight areas while ignoring the biggest score opportunities:
The ICC 314_PA_PH Engineer Grade A exam is an open book test. Open book is an advantage only if you’ve trained your navigation. With 80 questions in 3 hours, the exam is structured so you won’t have time to look up every answer from scratch.
Open-book performance improves fast when you study in the same rhythm you’ll use during testing:
Philadelphia requires an Engineer License for anyone working as an engineer in the city to operate or maintain equipment such as steam boilers, high temperature hot water boilers, steam engines, hoisting engines, and refrigeration machinery. Engineer licenses are issued in four grades, and Grade A is the broadest category for steam boiler, stationary, and refrigeration work.
Philadelphia’s engineer licensing program classifies licenses into four grades based on scope. For Grade A candidates, the City describes Grade A as covering steam boiler, stationary, and refrigeration engineer work. Anyone working as an engineer in Philadelphia needs to have this license, and the City outlines the core requirements for application and renewal.
The ICC Philadelphia bulletin lists approved references for the Engineer Grade A exam and notes that, with the exception of Ugly’s Electrical Reference, any edition of the listed books is acceptable. The bulletin specifies 2008 Ugly’s Electrical Reference for the electrical portion of the exam.
The best way to prep for Grade A is to study like a plant operates: systems interact. Boilers connect to feedwater and condensate systems. Controls influence combustion stability and safety. Electrical fundamentals support troubleshooting. Refrigeration knowledge applies to machinery operation and safe maintenance. Your exam prep should reflect that reality, while still following the exam’s weighting so your time goes where the points are.

The highest-weight category is Turbines, Design Auxiliaries, and Operations (15%). Other major areas include boiler operations/maintenance/safety, water treatment, combustion and fuels, and boiler design/principles.
Yes. The content outline includes dedicated sections for Electrical (7%) and Controls – Pneumatic and Electronic (7%), so you should plan to practice these topics and their related lookups.
Because of the time limit, you won’t have time to look up every answer. Open-book practice builds speed: choosing the right reference quickly, finding the right chapter, and confirming details efficiently.
Study by content area and do timed question sets. When you miss a question, write down where the correct information is found. That builds navigation memory so you move faster and more confidently on exam day.
