Panels & Service

• 100-Amp vs. 200-Amp Electrical Service: What You Have and What You Need — How to read your service size off the main breaker, what 100 amps actually supports, the electrification loads changing the math, and the upgrade-versus-manage decision.
• Circuit Breakers Keep Tripping: Diagnosis — The three reasons breakers trip, overload, short, and ground fault, how to tell them apart by behavior, the unplug-and-bisect method, and when the breaker itself is the problem.
• Understanding Your Electrical Panel — A tour of the breaker panel: mains, buses, branch breakers, the labeling job worth an afternoon, the panels with known defect histories, and what stays behind the dead front.

Safety Devices

• Extension Cords and Circuit Overload Hazards — Why extension cords rank high in electrical fire statistics, gauge and length math, the appliances that should never run on cords, and the permanent-wiring line cords must not cross.
• GFCI and AFCI Protection Explained — The two protective technologies beyond the ordinary breaker: what ground fault and arc fault protection each detect, where code wants them, monthly testing, and nuisance trips.
• Grounding and Bonding Basics for Homeowners — What grounding and bonding actually do, why they are different jobs, the ground rod and water pipe electrodes, ungrounded outlet realities, and the bonding rules that touch plumbing.
• Smoke and CO Detector Placement, Types, and Lifespan — Where smoke and carbon monoxide alarms belong and where they misfire, ionization versus photoelectric, interconnection, the ten-year lifespan rule, and the testing calendar.
• Whole-House Surge Protection: How It Works — Where surges actually come from, what a panel-mounted surge protective device does, the layered strategy with point-of-use strips, and why grounding quality decides everything.

Wiring

• Aluminum Wiring in Older Homes: Risks and Remedies — Why 1965-1973 aluminum branch wiring earned its reputation, the connection problem at the heart of it, the approved repair methods, and what inspectors and insurers look for.
• Flickering Lights: What They Tell You — Reading flicker by its pattern: one bulb, one switch, one circuit, or the whole house, from LED dimmer mismatches to the loose service connections that count as emergencies.
• Knob and Tube Wiring: What Inspectors Look For — How knob and tube wiring works, why its original engineering was sound, the modifications and insulation that make it hazardous, and the insurance and replacement realities.
• Outlet Problems: Dead, Loose, and Reversed Polarity — The dead outlet checklist from tripped GFCIs to failed backstabs, why loose outlets are a wear item, what a three-light tester's codes mean, and the findings that end the DIY portion.
