Electricity, made useful.

Practical electrical tools and explanations shaped by 20 years of active-duty electrical work, technical instruction, and civilian facility assessment. Start with a voltage-drop estimate you can actually inspect.

Read the result

An estimate, not a shortcut around design.

Voltage drop is one decision in a complete installation. Use this number to test the run, then verify the rest of the system.

01 — DISTANCE

Enter one-way length

For single-phase and DC circuits, the formula doubles it for the outgoing and return conductors. Three-phase uses √3.

02 — CONDUCTOR

Size for more than drop

A low percentage does not prove adequate ampacity. Check insulation rating, terminals, ambient temperature, bundling, and the governing code.

03 — REAL LOAD

Use realistic current

Design current and starting behavior matter. Motors, long feeders, and sensitive equipment may call for a tighter target or a fuller impedance calculation.

Why Cyborg Electric

Field experience, technical instruction, and clear numbers.

From 1992 to 2012, Cyborg Electric’s founder served on active duty in the U.S. Navy Seabees as a Construction Electrician First Class (SCW), Retired, earning the Seabee Combat Warfare Specialist (SCW) device. After one year as a small arms weapons instructor, he spent three years teaching basic "A" and advanced "C" electrical school and earned Master Training Specialist (MTS). He graduated summa cum laude from Trident University International with a Bachelors of Science in Computer Science, then worked about three years as an Engineering Technician before moving into Facility Assessor Electrical work. His leadership experience includes serving as Team Leader for USMC and Army projects, and as the Electrical Discipline Lead for a group of 30 on the USMC project.
