GER Licensed Electrical Inspector study guide

GER Licensed Electrical Inspector · Work through your exam, one topic at a time.

The GER Licensed Electrical Inspector credential is a professional licensing designation for electricians and inspectors who verify that electrical installations comply with applicable codes and standards in the German market. It is aimed at experienced electrical practitioners moving into plan review, site inspection, and code enforcement roles, as well as working inspectors seeking formal recognition of their competence. The GER Licensed Electrical Inspector study guide has 8 sections and about 2,303 words.

01

Electrical Theory and Fundamentals

This domain checks whether you can apply Ohm’s law, AC power relationships, series/parallel rules, and voltage-drop math to field and plan-review problems. Expect single-phase and three-phase calculations, power factor, conductor resistance, and transformer or motor basics.

02

Wiring Methods and Materials

Wiring-methods questions test selection, installation limits, support, fill, and physical protection for raceways and cables under NEC Chapter 3, plus conductor ampacity and adjustment. NM cable is permitted in dry, protected locations but not in wet locations, exposed to physical damage, or in most hazardous locations.

03

Branch Circuits, Feeders, and Service Calculations

This domain covers branch-circuit ratings, receptacle and lighting loads, feeder and service demand factors, and the 125% continuous-load rule in Articles 210, 215, 220, and 230. Continuous loads are calculated at 125% for branch-circuit and feeder sizing.

04

Grounding, Bonding, and Overcurrent Protection

Grounding and bonding questions test electrode systems, conductor sizing, neutral separation, equipment grounding, and overcurrent protective device ratings under Article 250 and Article 240. A grounding electrode system must be installed at each service; metal underground water pipe, metal frame, concrete-encased electrode, and ground ring are common electrodes.

05

Electrical Inspection Procedures and Documentation

Inspection-procedure questions test the sequence of rough-in and final inspections, test methods, correction notices, documentation, and re-inspection. Verify the permitted scope and approved plans before inspecting; note any field changes that require revised plans.

06

Code Enforcement and Plan Review

Plan-review and code-enforcement questions test code edition adoption, document review, load-calculation checks, alternative methods, and the limits of official authority. Enforce the edition and local amendments legally adopted for the jurisdiction; do not apply a newer edition retroactively without authority.

07

Special Occupancies, Equipment, and Hazardous Locations

Special-occupancy questions test classified locations, health care, assembly, pools, emergency systems, motors, and transformers under NEC Articles 500–517, 680, 700, and 430. Class I locations contain flammable gases or vapors; Division 1 is normally hazardous, Division 2 only under abnormal conditions.

08

Safety, Liability, and Professional Ethics

Safety and ethics questions test NFPA 70E practices, lockout/tagout, PPE, conflicts of interest, impartial enforcement, and liability documentation. Energized work requires an energized-work permit, arc-flash risk assessment, and appropriate PPE; de-energizing is the default.
