i have two water pumps that i had to cut the plugs off of to pass the cord through grommets. the wires are green, black, and white but are twisted and i can't figure out which wire is the ground and which ones should go to the plugs. anyone know what the convention is for wiring plugs? green and black are power and white is ground? thanks.

gP

I'm no sparky....but I think black and white are yer power wires and the green is the ground.

anyone else have a say?

ww

Hey GP,The black wire is the power.The white wire is the neutral.The green wire is the ground. On the plug there is one splade that is bigger that is the {white wire} neutral.The smaller splade is the {black wire} power.There's a green colored screw this the ground. If you get a plug from homedepot it will have markings W, B, G hook it up w-white b-black g-green. Peace

black is positive
white is negative
green is earth ground

according to electrical convention rules

Actually white is neutral. I'm not sure if neutral is synonymous with "negative". I'd be interested in knowing for sure either way though. Too much knowledge is usually a good thing, relatively speaking.

Hey The Corsican, You are right. The white wire is the neutral witch is in electric symbol {-} is negative.The black wire is the power and is the positive symbol {+}.The Green wire is ground {earth}.In electric codes the white is always neutral and the green is ground.In most homes the wiring is romex 12-2 with a ground.One white one black and a bare wire.The bare wire is the ground always. 220ac is 3 wires and a ground wire.One black one red one white and one green.The power is carried on the black+ and the red+ wire.The white is always - neutral.What I'm saying is the white and the green wires are always w-neutral and G-ground.All power is black,red,blue,yellow.This is how they have more then one circuit in places like strip stores and wal-marts.That help or did it confuse you more? Peace

No, it helped.

I wanted a fuller understanding and didn't want to question Rev.Johnson like I was some sort of know-it-all. So the white wire can be called neutral or negative without any misunderstandings or confusion Toke?

Thanks brother,

Quite the opposite. I am an electrician, and If you are in the U.S. the GROUND will be the GREEN wire. If the pump is 110V Your white wire will be the Grounded conductor, sometimes erroneously referred to as a negative, correctly called a neutral wire. Your Black wire should definitely be the "hot" wire or current carrying conductor. If it is 220, both will be hot and carry a potential to ground, or 120v measured across the ground and the conductor in question. If it is a 220 pump, then the wiring will not matter as to which lead connects to the black or white, just don't connect one to ground. If it is 120, there should be an indication on the pump leads as to which is the hot, and which is the neutral, or on the wiring diagram that is supplied with most utilization equipment. For 220, you only need two wires. Some equipment that runs on 220 will have extra's like timers and such that operate on 120 where a neutral will be required. In that case there will be an additional solid non green color for the additional current carrying conductor. Hope this helps. Please ask if you need any clarification.

This has to do with the differences between Alternating Current systems and Direct Current Systems.

Current carrying conductors are also called Ungrounded conductors in an A/C circuit. Ground is actually a grounding or equpment grounding conductor and the neutral is a grounded conductor, Both the neutral and the grounding conductor eventually terminate to an earth ground, but the paths by which they get there are the reason to maintain the conventions. Grounding is primarily a safety feature (NEVER BYPASS, IT IS ESSENTIAL TO LIFE SAFETY) and requires the least amount of resistance, or impedance as possible. Actual regulations for this exist in NFPA 70 or the NEC. The Neutral Conductor carries the unbalanced load in most (what are reeferred to as edison based) systems of the type most are familiar with. It may have a current flow (though when balanced this is not so) so ALWAYS treat it as if it does. I've been hit by neutral shocks before and they are some of the worst, because you end up becoming the current's path to ground almost exclusively. I'll stop ranting now, but any questions are always welcome. I love to help.

Also, if by plugs you mean cord caps, the large blade, or the one with a silver screw, will always be your neutral with 120. the skinnier one, as well as the bronze/copper colored screw will be your "hot" wire, usually black but not always, such as when it's coming from conduit where a different color was intentionally or unintentionally run. This also applies to receptacles or "outlets".

In alternating Current Circuits the current is constantly changing direction, In the U.S. at 60 times per second, known as 60 Hertz. In European countries (besides being 220 for most everything) as well as Canada, I believe, the standard is 50 hz. Direct Current will always flow from the electrically negatively charged side to the positive, either continuously or pulsating depending on the derived source and corrections implemented. It is actually not a compatible idea to equate the two conventions of "neutral" and negative.

Awesome posts Jigsy, it's nice to have some professionals around to make sure us amateurs don't wind up frying ourselves.

hook the white wire to the silver screw on plug and black wire to gold you will be in luck and be sure to hook ground


simpliest way ever

we should have some diagrams like this available for members to help reduce the electrocution hazard

I'm not so computer literate, but I may be able to manage. Do you think there might be a call for a sub-forum for things of an electrical nature? I noticed at least one other electrician somewhere around the archived posts giving rather sound advice. Forgot their handle, and don't know if he/she still participates, but some of the posts may have included drawings/diagrams.

I think that would be a good idea. There are a lot of DIY types on this forum.

Here is a pictorial representation of what is meant by this statement in regard to the receptacle wiring standards.

Edit: This is True of United States including Hawaii and Alaska. Other locations worldwide use different standard, so it will be necessary to take your location into account. An example, The U.S. virgin Islands use The green wire as a current carrying conductor, or that was true years ago when I was in school. This convention may or may not have changed. If anyone needs assistance interpreting their local standard I will be happy to help.

Why does the 20 amp receptacle plug-in a bit different from the standard receptacle Jigsy? There are lateral spaces on the plug-in.

"If at first you don't succeed, it wont hurt to smoke a little weed!"

This is a NEMA (National Electrical Manufacturers Association) standard. It helps to identify receptacles that are rated to handle 20A safely. For Equipment over 15A and under 20A A similar cord cap with the lateral protrusion on the neutral conductor comes supplied on the cord cap and will not be compatible with 15a receptacles. In residential dwellings it is permissible in most cases for general use branch circuits to install 15A receptacles on a 20A circuit with the idea being most appliances in the home do not draw upwards of 15A. If you have an appliance that does, it will not fit the 15A receptacle limiting the danger this implies(if the original cord cap supplied is intact). For Commercial wiring, where everything is much less ascribed to convention and is designed to spec for more specific purposes, and The NEC (National Electrical Code NFPA 70 published by the National Fire Protection Agency as the THE DEFINITIVE LAW in THe U.S.) proscribes circuits rated under 20A, you will find many more 20A Receptacles. [Note that a 15A cord cap will be able to fit the 20A receptacle and this is a safe condition. A 20A cord cap will not be able to fit a 15A receptacle as this would be unsafe and a high potential for fire hazard.]- this in the brackets is the simple answer to that question.

Note: Do not install 20A Receptacles on a 15A branch circuit, a circuit that is supplied by a 15A circuit breaker or fuse (overcurrent protection). Most of these 15a circuits will be supplied by 14 guage wire, but not all. Identify the overcurrent protection device's rating to be sure, this will be the breaker/fuse that kills the circuit.
