Lobster tank GFCI protection?

I think the bigger problem is grease being poured down drain, then increased amount of solids from the disposer to get hung up in the grease. Eggshells are abrasive if you get them to flow may actually do some cleaning along the way.

The problem with eggshell fragments is that they are heavier (denser) than water and tend to settle out of the stream as it flows away from the house. Grease is a problem, too, of course.

I am picky that way. To each his own I suppose....

I agree. And in this whole debate the NEC clearly gives examples- or lines of thinking showing the concern is missing EGCs more than water.



The definition of Ground-Fault Circuit Interrupter appeared in Article 680 (in the 1968 edition) as “a device whose function is to interrupt the electric circuit to the load when a fault current to ground exceeds some predetermined value that is less than that required to operate the overcurrent protective device of the supply circuit.” GFCI was still only one of the protection methods permitted for underwater fixtures. An interesting requirement was that conductors on the load side of the GFCI device were to be kept entirely independent of all other wiring and electrical equipment.



It was not until 1971 that GFCI protection became a “required” protection method. Even though underwater lighting fixtures were the first allowed this protection they were not the first required to have it. A failed grounding connection presents an electrical hazard, particularly with the number of handheld power tools and extension cords used around a construction site. So the first GFCI requirement (first simply because it occurred in Section 210-7) was for all single phase, 15- and 20-ampere receptacles used at a construction site. A few sections further, GFCI protection was required for all outdoor 120-volt, 15- and 20-ampere receptacles in residential occupancies, essentially for the same reason as for construction sites. This section also specifically permitted GFCI protection for “other circuits, occupancies and locations” if added protection was desired. In Article 680, protection included all electrical equipment used with storable pools and all receptacles within 15 feet of an indoor pool . The expansion of GFCI protection had begun.

Ground-fault circuit-interrupter protection requirements took time to expand. Concerns about the new technology, false tripping, financial burden, and the lack of data were cited as reasons. Still, 210-8(a) of the 1978 NEC added GFCI requirements to garages of dwelling units, partially due to concern with the amount of grounded (concrete) surface, and the fact that many hand-held tools did not have an equipment grounding conductor (for the younger crowd who have only used double-insulated ABS tools, metal used to be the hand-held power tool housing material of choice). Data regarding a grounding system that was verified as being intact supported the addition of an exception to the 210-8(b) construction site requirements. This exception introduced the assured grounding program as an alternative to GFCI protection. GFCI protection also became a requirement for marina receptacles (Article 555).

More Exceptions

Exceptions for garage receptacles that were not accessible — or were used for appliances in a dedicated space — first appeared in 1981. Thirty years ago, many appliances had high leakage currents, and ones with motors often were capable of tripping a GFCI device; therefore, fixed appliance locations were exempted. Non-accessible receptacles — such as on the ceiling for a garage door opener — were likewise exempted, with the expectation that the receptacle would not be used with extension cords or hand-powered tools.

The GFCI requirements expanded in 1987 to additional dwelling unit receptacles. The Code required the installation of at least one receptacle in a basement. With the concrete and portable tool use in this area, GFCI protection became a requirement for that one receptacle. The intent of the wording “above the countertop and within 6 feet of a kitchen sink” was clarified to exempt appliances (disposal, refrigerator, etc.) from the GFCI requirement. Additionally, dwelling boathouses (due to the nature of the location and the use of portable tools) became another protected location. The receptacles in commercial garages (Article 511) were included for the same reasons as those in a dwelling unit garage.

Many pool pumps at private clubs and apartment complexes are hard-wired, and these pools are often maintained by personnel not familiar with bonding and grounding requirements. The concern for protection of the public using these facilities warranted adding the GFCI requirement in the 1999 Code to 125- or 240-volt, 15- and 20-ampere pool pump motors, whether they were direct connected or cord-connected. This edition also brought another change to temporary installations (which were at that time in Article 305) when it expanded GFCI requirements to cover 125-volt, 30-ampere receptacles as well as any other receptacle used temporarily.

Okay, then why post all that other stuff that I am not going to read. Distraction.

If have a single point. State it. Clearly, Concisely, and Coherently.

I do and I did. The rest is backing up that point when called into question. I am glad I can use the NEC to do that.

Every drain coming from a kitchen I have ever had to unclog, was clogged because of grease buildup. Larger amounts of solids from a disposer just happens to get stuck easier because of grease already in the line. Once you get into main lines grease isn't as big of a problem anymore. for one thing it has already cooled before it gets there and either stuck to walls of pipe upstream or solidified and washed on through.

About the lobster tank, correct. But again, the NEC shows that the concern in GFCIs was more about missing EGCs and less about water.


Clearly: If everything the is energized in and around the lobster tank has an EGC I believe IMO there is no risk.

We never said there was. The point was that in comparison to an EGC or an EGC and and a GFCI, given the parameters of THIS particular install, GFCI was cheap protection given any real or potential danger. The risk is always evaluated on an individual set up or simply follow code.

And, I think we can both agree on this- for $10 nothing will be lost :)

Guy in Arizona bought London Bridge once... and moved it to the states.. so, could be you could buy a bridge in NY... I once bought a few acres in Florida... cheap taxes..lol... but let Florida have the land a few years later because they would never approve my house plans.. something about being in a protected zone..lol..
