Electrician Lab
Lab notes from electrical training and hands-on practice with control circuits, devices and conduit.
Inside the Electrical Lab
Electrical training exercises connect wiring diagrams to real devices. This page collects practical skills from formal electrical training and helper experience, with space for photos and documented outcomes.
1. Switching and receptacles
Practice includes single-pole switching, 3-way and 4-way switches, split receptacles and GFCI protection. A useful exercise is tracing the supply, travelers, load and return conductors from a diagram before making connections.
2. Conduit and boxes
Training topics include EMT hand bending, offsets and four-point saddles, 1900 boxes and NEC 314.16 box-fill calculations. Measurements and conductor allowances must be checked against the actual installation and applicable code edition.
3. Motor control
Explore contactors, starter coils, overload protection, control wiring and step-down transformers such as 120/24 V. The focus is understanding why a motor control circuit energizes or stops—not presenting unverified live-wiring instructions.

These are educational descriptions. Never perform live electrical work based on a portfolio page; follow lockout/tagout practices, applicable codes and qualified supervision.
