I will get why in a moment. On the back wall we can see the two wires going to the gold plated studs. This is where your green grounding wire would be cut and connected to. Inside we can see the two diodes which allow current to flow in both directions but at the same time blocking voltages below 1. Well,there is a very good reason for that.
Think back to when I described where a GI gets installed? What happens if one or both of those diodes gets blown? Honestly ask yourself when you ever heard of someone testing a GI? Hot cases and metallic parts of your boat spell the potential for electrocution or death to occupants or to swimmers by electric shock drowning.
Without the safety ground connection to shore the fault protection devices will not trip as they should. Below is a direct quote from Captain David Rifkin. David is perhaps the leading expert in marine electrical shock drowning deaths, bonding and corrosion. How many boats in your marina? So if 5 of those boats are completely lacking a green safety ground wire, do you want to go swimming in your marina?
Course we all know we should never swim in a marina, but it happens. The ABYC standards for galvanic isolators have changed a few times over the years. This was in the form of a remote lighted panel so an owner could glance over and know they had a safe and operational GI with the safety ground intact.
This advancement brought simplicity, and no monitoring, back to the GI and did away with the idiot lights and related circuitry. Unlike traditional diodes that tend to fail open the fail safely diodes fail closed and all you lose is galvanic protection. The designation FS or fail safe means that these devices fail closed instead of open as a normal diode would.
According to Henry T. A pretty impressive feat considering the number of failures that occurred with the older technology, like the one you see here. If adding a GI, for regular dock side use, we strongly advise installing a fail safe product.
The diode symbol can be seen on the left hand side of the meters screen. If the diodes are working you should see a reading of. If the diodes are bad you will not get a reading or will get the OL message open leads if using a Fluke. Older style galvanic isolators like this fail open.
Remember, the current needs to be able to flow in both directions, just like a piece of wire, and it is possible for one side to be blown and the other side still be fine.
Here the reading is. Despite being a relic from days past, this isolator is still operable. If however you have an old isolator like this, and you keep your boat at a marina, I would strongly advise upgrading it to newer ABYC compliant fail-safe unit. The only other alternative is to regularly test your GI to ensure it is operational. I certainly love our Fluke test equipment, we abuse the living snot out of it, and it survives. However, for a DIY, especially one on a budget, even an inexpensive meter will do.
You just need to ensure it has a diode test function. On this meter the diode test function shares a dial position with the audible tone continuity test. UL Certified ProSafe FS installs easily and does not require a dedicated monitor to verify the operational status of the galvanic isolator as required by non Fail Safe Certified galvanic isolators.
Certified by Underwriters Laboratories UL. Insures shore power safety ground wire is maintained through the isolator. Flat Pack High Power Semiconductors Robust high power diodes allow the FS Series to meet the new Fail Safe criteria for conducting inrush currents of 5, amps for the required duration period.
Innovative Design The FS 60 will cool itself in the event it must conduct current insuring cooler operation in this mode.
