Mike Holt 30-day review (review 8)

Why I tried Mike Holt for 30 days

I've been wiring houses and light commercial for 14 years. Mike Holt's name shows up everywhere in this trade, his illustrated code books sit on half the apprentice trucks I've seen. I wanted to know if the digital subscription holds up the same way the print does, so I paid for 30 days and used it on real jobs.

The test was simple. Every time I needed to look something up in the field, I tried Mike Holt first before falling back to my usual references. Service calculations, GFCI placement under NEC 210.8(A), grounding electrode questions under 250.50, the kind of stuff that comes up on a normal Tuesday.

What works

The illustrations are still the strongest part. When I had to explain to a GC why a panel in a finished basement needed working space per NEC 110.26, pulling up the diagram on my phone closed the conversation in under a minute. Those graphics translate code language into something a non-electrician can actually see.

The video library is deep. Hours of content on grounding, bonding, transformer calcs, motor circuits. If you're prepping for a Master's exam or trying to internalize why a rule exists, the explanations are solid and the instructors know the trade.

• Strong visual explanations of complex articles like 250 and 690
• Code change videos when a new cycle drops
• Practice questions that match the style of state exams
• Forum access where you can ask code questions and get real answers

Where it falls short on the truck

Search is the problem. When I'm standing in an attic with one bar of service and I need to confirm the ampacity adjustment for four current-carrying conductors in a raceway under 310.15(C)(1), I don't want to scroll a video index or land on a forum thread from 2019. I want the table, the rule, and the exception. Fast.

Mike Holt's platform was built as a training library first. That shows. Looking up a single article means sifting through course modules, study guides, and discussion threads. The illustrated code book PDF helps, but PDFs on a phone in direct sun are a known pain.

Field tip: if you're using any digital reference on a roof or in a crawl, test it offline before you need it. Streaming video at the bottom of a meter base is not a plan.

Pricing reality check

The subscription tiers add up if you want full access. Individual courses, exam prep bundles, and the continuing education packages are priced for someone investing in a career step, not someone who needs a quick lookup at 2pm on a service call. That's fair, it's what the product is built for.

For a journeyman who already passed the test and just needs working code answers daily, you're paying for a lot of training material you won't open twice. The math changes if you're prepping for Master's, teaching apprentices, or running CEU hours. Then it's worth it.

1. Apprentice or exam prep: high value, the videos and practice questions are worth the price
2. Journeyman doing daily lookups: overkill, you're paying for a school
3. Master or contractor running CEUs: solid, especially around code change cycles
4. Inspector or AHJ reference: decent, but you probably already own the print set

How it stacks against a fast lookup tool

This is where it gets honest. Mike Holt is a teacher. The platform reflects that. If you want someone to walk you through why NEC 250.122 sizes the equipment grounding conductor the way it does, the videos are excellent. If you want to type "EGC for 60 amp feeder" and get the answer in two seconds while a homeowner watches, that's a different tool.

Most of my 30 days, I ended up using Mike Holt for the deep dives at night and something faster during the day. The two uses aren't really competing, they just both cost money and only one of them earns its keep on the truck.

Real call from week three: customer asked why the hot tub disconnect had to be six feet away. I needed 680.12 in twenty seconds. I got it from a different app. Then that night I watched the Mike Holt video on Article 680 and learned three things I didn't know.

The verdict after 30 days

Mike Holt is the best electrical training resource on the internet. That's not a small thing. The instructors are sharp, the illustrations earn their reputation, and the depth on grounding and bonding alone is worth a month if you've never sat through it.

It's not a field reference. It was never trying to be one. The mistake is buying it expecting a fast NEC lookup and getting frustrated when it asks you to watch a 12 minute video to answer a 10 second question. Match the tool to the job.

If you're studying, buy it. If you're wiring, keep something faster on your home screen and use Mike Holt for the long evenings when you actually want to understand the code instead of just cite it.
