The Modern Home Electrical Master Reference

Stop guessing at wire sizes - look them up.

Most electrical mistakes are not mistakes of skill, they are mistakes of memory. The Modern Home Electrical Master Reference is the book you keep open on the bench while you work: every table, rule, and number a homeowner or DIY electrician actually reaches for, in one place, with 83 full-color figures that show the answer instead of describing it.

Inside you will find:
• Look up copper ampacity on both columns that matter - NM cable and wire in conduit
• Size a box or a conduit correctly, with a complete worked example
• Identify any common NEMA receptacle, drawn to scale
• Get grounding and bonding right, including the one-bond rule
• Run a full residential load calculation from start to finish

This is not a project book - it is the reference you open while the project is already in your hands. Written in plain English for homeowners, DIYers, and apprentices, and aligned to the 2023-2026 National Electrical Code.

Always turn off power at the breaker and follow local code. When in doubt, consult a licensed electrician.
