Hubbell Helps Solve Isolation Transformer Dilemma

Hubbell Helps Solve Isolation Transformer Dilemma

Well I’m just back from the annual IBEX show in Tampa Florida and have some good news for those installers and boat builders that use shore power isolation transformers. Last January our industry was a bit stunned when the long time supplier, Charles Industries dropped its marine products line, all rather suddenly and without much notice to its customers by Continue Reading »

LED’s Cause Radio Frequency Interference

LED’s Cause Radio Frequency Interference

Recently I’ve been getting a lot of queries about whether of not marine LED lighting systems can be the cause for radio frequency interference, more commonly known simply as RFI. The short answer is yes these LED systems can indeed be a source for RFI. That said, this requires a bit of further explanation. In my book Advanced Marine Electrics Continue Reading »

Our friends over at Hubbell have just introduced an inexpensive solution for older boats not equipped with ELCI devices to shut down the shore power to a boat that has some excessive ground fault leakage issues on board. Although this new circuit checker won’t actually shut anything down, and it doesn’t specifically identify ground faults from equipment installed on board, Continue Reading »

Yanmar Provides LION Battery Bulletin

It seems that our friends at Yanmar may have been having some issues with some customers swapping out the batteries on their boats for lithium ion units. It is imperative to note that there is a LOT more to do with your boat when switching to lithium technology than merely swapping out the batteries. A proper BMS (battery management system) Continue Reading »

Electrical System Breakthrough for Boats

Magnum Energy has just announced what I consider to be a major step forward for small boat electrical systems. The MagnaSine hybrid inverter/charger is a pure sine wave inverter that also integrates the ability to provide supplemental AC power when needed on board. I see this as particularly useful feature on boats using smaller AC gensets either due to weight Continue Reading »

Stop Saildrive Corrosion

Stop Saildrive Corrosion

I recently penned an article for the June/July 2017 issue of Cruising World magazine entitled “Driven to Diligence“. The article discusses the growth in market share for sail drives in cruising sailboats  as well as some of the issues relative to their maintenance and health. If you own a boat with a sail drive or two installed, I highly recommend Continue Reading »

New Hubbell Shore Power Y-Adaptor Solves a Common Problem

    What boater hasn’t faced the problem of pulling into a new marina for the night, to find it only offers 30A power when the boat runs on 50A? The YQ230 Intelligent Y-Adapter from Hubbell Marine gives owners the freedom to travel without concern. It allows them to safely connect any 50A, 125/250V AC marine cord set to two Continue Reading »

Electromagnetic Interference On Your Boat

Electromagnetic Interference On Your Boat

Electromagnetic Interference (a.k.a Crosstalk ) As mentioned earlier this month I’m sharing some of the points brought out when I attended the new ABYC/NMEA joint training program offered in Ft. Lauderdale, FL. One of the topics that came up during the NMEA portion of the program discussed electromagnetic interference. This is a topic that I know I’ve discussed here before. But, Continue Reading »
