    I believe that is his goal. A failed heater won't take out his entire system.

    I don't know if this is relevant- just my two cents but if you somehow managed to have two gcfis on the same circuit they can trip easily. I say this because a power washer ( which has a built in gfci) will trip if plugged into an already protected gfci circuit.

    Oh I guess I rebooted my Apex about 3 times in the last 48 hours. That must be what tripped the GFCIs.

    The GFCIs on the heaters tripped again with out the EB8 losing power. I'll try putting them on outlets 4 and 8.

    When you unplug them, do they trip?

    The listing on Amazon doesn't say they trip on loss of power, but some GFCI's do. Normally they are pretty clear on that.

    When I unplug them they trip. Also when power from channel goes off they trip too. Do you know if the listing says if they do stay untripped on loss of power?

    I got these things through Amazon and it's nearly impossible to return things to Amazon.

    I was doing a search on GFCI's and a listing said it was Automatic Reset, is this what I want?

    GFCI's that trip on a loss of power are pretty uncommon at this point. But yes, Automatic Reset is an older term used back when GFCI's needed power to stay latched "on".

    I need to buy gfci adapters (can't change the sockets)

    I will be plugging my powerbar into the gfci and my heater, filter, and pump will be running on this( not my lights)

    If I use a grounding probe can it be plugged into the powerbar?

    Any recommendations on good adapters?

    The Apex power bar, the EB8, has a resettable fuse. Is this any protection of equipment? What about equipment I don't have plugged into my Apex, should that be protected by GFCI's? If all equipment can't be protected which is the most important ones to protect besides the most expensive, I'm guessing the ones that use the most wattage?

    My apologies for the late response... I missed the notifications on this thread.
    I think this one works well at a reasonable price.

    Yes, you can plug your grounding probe into the powerbar.

    Fuses such as in the EB8 are for overcurrent protection. GFCI's are to prevent electrical shock. Typically you would want to have overcurrent protection on your larger devices and GFCI's on any electrical devices in your tank or likely to get wet.

    Since you are doing differential protection trip checks it is likely the problem is in the relay and not the breaker.

    One common issue is that the differential restraint current may be set too low to allow a trip during a standard test. Depending on settings you may need to be at or near fault level currents to generate a differential trip.

    So what is the consensus here? Is GFCI + ground plug something that should be required to have a reef tank? There are probably 1 million+ reef tanks in the US alone has there been any reported cases of electrocution(to death) or any or major electrocutions links plz? The reason I ask is because I am entirely ill informed about electricity but I do have several reef tanks and have had leaking current several times from cheap chinese pumps where I could feel a tiny and i mean tiny buzz. Does it matter what size gear we have in the tank? I have a 5 watt return pump and a 50w heater and thats it inside the tank. Does it matter if we are wearing rubber shoes, rubber gloves and standing on a wood floor vs barefoot on a solid metal copper floor? I think all of these variables maybe should be taken into consideration.

    There's your link.

    Do what you will. Take all of your variables into consideration, who cares.

    GFCI and Probe will protect
    Your Investment
    Your Fish
    Your Coral
    Your Family
    Your Friends
    And You

    Spend the dang 20 bucks.
