Gcfi

[Aere]

anyone for or against these? Woke up this morning and it cut off, leaving my sump to overflow, and water everywhere. And this happens about once a week.

Better options or ideas?

Do you have a check valve on your return line? Or possibly need to get a larger sump so this will not keep happening.

Check all your equipment make sure it's working properly
Any water falling on it
Or humidity
What kind of powerstrips or controller are you using?
Or sometimes when there's too much back pressure on your pumps
It'll cause the gfci to trip

there was a little salt build up on the plug, I will have to move it I suppose. The equipment all seems to be in order. Its getting some splash from the Refugium I am sure. Just a pain in the butt!

Check for stray current. If the GCFI is trippin' it's for a reason. On the one hand it sucks that it turns things off...on the other it does tell you something is wrong. My opinion, fix the cause not the symptom (GCFI).

I am using a grounding probe, would that fix stray voltage? or are you referring to something else?

A grounding probe will help with stray voltage but I would still replace whatever is leaking voltage into the sump. Also, once a gfci gets old, it is more likely to fail, so if its an older GFCI i would replace it with a new one just in case.

A grounding probe just prevents you from becoming the ground for stray voltage (aka you're not the one getting electrocuted), but it doesn't solve the issue. If you do have stray voltage you need to figure out what device it is and then either repair or likely replace it. Use a "pen" voltage meter and check for stray voltage by turning off one item at a time. When the pen stops beeping then you know the unplugged item is no longer leaking voltage. But before that, unplug the grounding probe and use the pen to see if stray voltage is the issue in the first place.

If it's not stray voltage then replace the GCFI with a new one and make sure it's installed correctly.
