Electrical reference graphics to print and save

Dear Mike,
First… Thank you for your No~Shock~Zone book on RV Electrical Safety. I’m only half through and love it. The way you explain things is wonderful and easy to understand. Also following you on RVtravel each week.

My question is, the book is black and white and I would really like to make some quick reference guides (laminated) to keep with my electrical RV cord and test equipment. Is there a location (internet) showing all the colored Quick Reference Guides in the back of your book that I can print?

Thank you. —John Renicker

Dear John,
I’m happy to post them all here. On this page you’ll see them as thumbnails to save download time. But if you click on a graphic it will open up as a high-resolution file suitable for printing.

Hope this helps….



















Let’s play safe out there….

I am ordering your book – I am very grateful that you share your expertise! I have shared your name and info on other sites with others who had hot skin conditions, so many people were able to learn from your advice. I thought you’d get a kick out of the listing for your book on Amazon. How impressive that you published it January 1, 1600 – certainly shows you have more years of experience then anyone! 🙂

Mike, need help with LED parking light bulb (2007 Ford E-350) installed front LED parking/blinker bulb, fast blinking so I ordered 6 ohm resistors, 0ne side works ok the other side works correctly until I turn on parking or head lights, then dash light indicator comes on and stays on with no blinking turn light. Second item how much power in being wasted with the inline resistors, is LED a good choice when power robbing resistors are needed.
Thanks Pete

Thank you for posting these diagrams. It is very refreshing to find someone more interested in being helpful than in making a buck.
Good explanations as always!

Thank you and the 30a cord is much easier to handle.
Does not make any difference if 30 or 100 amps all of my outlets are on one circuit and go thru a 20amp breaker in the inverter! Have to be careful what is plugged in at the same time.
It is a 2004 Safari Trek, built by Monaco.

Yes you are. You need a 30-amp to 50-amp dogbone adapter plugged into the pedestal. Then plug your 50-amp surge protector into it, and plug your RV’s shore power connector into the surge protector. Of course you now only have 30 amps of power instead of the 100 amps available from a 50 amp outlet.

General question, if I use a 50amp surge protector on a 30amp circuit, am I still protected? Some electrical posts have only 30amps available.
Thank you
