Guides + blog
The math, in plain English
Guides and explainers from a Master Electrician. The library runs 114 posts - car guides, state pages, and NEC explainers. Below is the short list worth reading first, then every guide grouped by what it answers.
Most homes with 200-amp service have room to add a 40-amp EV charger without a panel upgrade. NEC 220.83 - the section written for an existing home adding a load - applies demand factors to your actual connected loads, and in most cases the resulting demand leaves capacity for the charger circuit. Whether your home is in that majority depends on what you already have running. That is what the NEC 220.83(A) load calculation tells you (with 220.82 and three more methods shown as cross-checks). I charge $49.99 to run it on your panel.
Why most EVs do not need a panel upgrade
The NEC optional methods - 220.83 for existing homes, 220.82 for new services - give credit for what your home actually uses, not the worst case.
Reading your panel like an electrician
Find the main breaker, count the slots, learn what brand and amperage actually mean.
The 80 percent rule, in plain English
Why a 50A circuit only carries 40A continuous, and why that matters for EV chargers.
Picking the right Level 2 charger for your panel
Why 40A is enough for most homes, and when 48A is worth reaching for.
Permits, timelines, and what installs really cost
The permit is not optional - what it costs, how long it takes, and why it protects you.
NEC 220.83, the method for most existing homes
A step-by-step walkthrough of 220.83(A) and (B) - the load calculation that applies when you already have a panel and are just adding a charger.
Can a 48-amp charger go on a 100-amp panel?
The breaker question (NEC 625.41) and the service question (NEC 220.83(A)) are separate - and only one of them has a fixed answer.
What it costs to find out if your panel is ready
A free rough self-check, a $49.99 ChargeRight assessment, or a $150-$300 electrician visit - what each one actually buys you.
Is ChargeRight legitimate?
What the report contains, who built it, what it is not, and the refund policy - with links back to every page it is copied from.
ChargeRight vs. hiring an electrician
What a $49.99 assessment covers vs. what a licensed electrician's on-site visit covers, and why report-first-then-electrician works.
What's actually in an EV load calculation report
A section-by-section walkthrough of every part of a ChargeRight report - the verdict, the NEC method breakdown, the panel photo, the hazard check, the electrician checklist - and what each part cannot tell you.
How ChargeRight calculates your NEC load
The public calculation spec: every method the engine runs, how the binding method is chosen, the inputs, the exclusions, the rounding rules, and worked vectors you can check by hand.
What size electrical service do you need for an EV charger?
100A vs 125A vs 150A vs 200A: what each size typically means, what actually decides it, and why the load calculation - not the panel label - is the real answer.
That is the short list. Every post in the library is linked below, and your car and state are also indexed under cars, locations, and videos.

NEC code explainers12
Aluminum Wiring and EV Chargers: NEC 110.14, CO/ALR, and the Two Aluminum Problems Homeowners Confuse (2026)
Original 1965-1973 aluminum branch wiring is not the same as a modern AA-8000 aluminum EV feeder. A Master Electrician walks the NEC 110.14 termination rules, CO/ALR vs AL/CU devices, anti-oxidant compound, and the $49.99 NEC Article 220 calc that locks the wire size before the quote.
EV Charger on a Home Generator: The NEC 702.4 Load Management Rule That Decides Whether the Charger Stays On (2026)
A 48A EV charger pulls 11.5 kW continuous. A typical portable generator delivers 7 to 10 kW. A Master Electrician walks NEC 702.4(B), NEC 702.5, NEC 625.42, and the NEC Article 220 math for backup power and EV charging, then the three install scopes (manual interlock + load shed, automatic transfer with EVEMS, V2H instead of the generator) before the 2026 hurricane season turns a transfer-switch question into a $4,000 mistake.
Where Your Panel Cannot Go: The NEC 110.26 and 240.24 Rules That Fail EV-Charger Inspections (2026)
An EV-charger inspection can fail before the inspector ever looks at the new breaker. A Master Electrician walks NEC 110.26 working space (3 ft depth, 30 in width, 6 ft 6 in height) and NEC 240.24 panel-location rules (clothes closets, bathrooms, over steps, handle height) and the five failed-inspection patterns homeowners hit at quote time, the same ones that tripped up installs before the 30C placed-in-service deadline closed June 30, 2026.
Summer Heat and Your EV Charger Conduit: The NEC 310.15(B) Ambient Temperature Math Most Installers Skip (2026)
A 50A circuit on paper can land below 50A after summer derating. A Master Electrician walks NEC 310.15(B)(2)(a) ambient correction, NEC 310.15(B)(3)(c) rooftop adder, and NEC 110.14(C) termination rules, the conduit-derating math most quotes skip in attics, on south-facing walls, and within 7/8 inch of a roof.
How ChargeRight Calculates Your NEC Load: The Public Calculation Spec
The same math, reproducible. Every method ChargeRight runs (220.82, 220.83(A)/(B), Standard Part III, 2026 preview), how the binding method is chosen, the inputs, the exclusions, the rounding, the NEC 230.79 verdict test, and worked vectors you can check by hand.
NEC 2026 EV Charger Rules: What Changed and What It Means for Your Install

NEC 220.82 Explained for EV Chargers: Compare 220.83(A) (2026)
Learn the NEC 220.82 demand-factor math and when it applies. Existing homes adding an EV charger normally use 220.83(A). By a Master Electrician (IBEW 369).
Adding an EV Charger to a Solar Home: The NEC 705.12 120 Percent Rule Trap (And the Five Cheaper Fixes) (2026)
Your solar installer sized the panel for solar, not solar plus an EV. A Master Electrician walks NEC 705.12(B)(3), the 120 percent busbar rule that decides whether your 200A panel can legally accept a 60A EV circuit, and the five fixes that beat a panel swap that typically costs $2,000 to $4,500.
Two EVs, One Panel: The NEC 625.42 Automatic Load Management Rule That Beats a Service Upgrade (2026)
Two Level 2 chargers on a 200A panel does not automatically mean a service upgrade. A Master Electrician walks NEC 625.40, NEC 625.41, NEC 625.42, and the NEC Article 220 math for two-EV households, then the three real installs (power-sharing on one feeder, two separate circuits, sequential charging). The 30C credit expired June 30, 2026, so the listed automatic load management system, not a tax credit, is what makes a panel swap unnecessary.
