"We recommend using at minimum a #6 AWG grounding cable"

"We recommend using at minimum a #6 AWG grounding cable"

"We recommend using at minimum a #6 AWG grounding cable"

(OP)
I know what they mean, but is this written properly? How would you write it?

RE: "We recommend using at minimum a #6 AWG grounding cable"

I might add a couple of commas, but other than that, it looks fine to me.

RE: "We recommend using at minimum a #6 AWG grounding cable"

(OP)
So if #6 is the minimum, then #10 must be fine and #22 is even better? 22 and 10 are both greater than 6, so the condition is met. Not what they mean of course, but I'm just wondering what the correct way of expressing the intent is.

RE: "We recommend using at minimum a #6 AWG grounding cable"

I suspect that they assume that people understand that as the wire gauge number goes UP, that the size of the wire goes Down. So while neophytes might be confused, anyone with an electrical background would know exactly what was meant.

RE: "We recommend using at minimum a #6 AWG grounding cable"

(OP)
Thank you. I'm looking for an unambiguous way of writing the intent.

RE: "We recommend using at minimum a #6 AWG grounding cable"

Note that I updated my reply after I reread your reply. That being said, I still think that the notation is acceptable since it's a safe bet that the people for whom this was written know exactly what was meant. Any attempt to clarify it with a treatise on wire gauges would look clumsy at best and condescending at worse (like my original response).

Thanks. A lot of what I write will be seen company wide, so I tend to look for ways to write to all audiences. Metric would make it easier.

RE: "We recommend using at minimum a #6 AWG grounding cable"

Perhaps: "We recommend using #6 AWG grounding cable or larger."

@fel3, I think it will be hard to find a clearer and more natural-sounding way of putting it than that.

RE: "We recommend using at minimum a #6 AWG grounding cable"

"We recommend using #6 AWG grounding cable or larger." … is the wire diameter larger, or is the cable larger ?

"we recommend using a grounding cable of #6 AWG or larger." ?

or flogging a dead horse …

"we recommend using a grounding cable of 0.162in diameter (#6 AWG) or larger."

RE: "We recommend using at minimum a #6 AWG grounding cable"

I would be more specific, delete recommended and simply say - "minimum grounding wire is to be #6 AWG"

RE: "We recommend using at minimum a #6 AWG grounding cable"

Artisi…

For an engineering specification, I agree that being specific (the root of "specification") like you wrote is the only good approach. Many consumer electrical items I have purchased (e.g. ceiling fans, light fixtures, etc.) include a recommendation (such as I reworded above), not a specification. Regardless, your approach is the correct one.

RE: "We recommend using at minimum a #6 AWG grounding cable"

Sorry but in my opinion one MUST NOT ASSume that an interested party has sufficient electrical knowledge to understand that wire diameters get smaller as gage number goes up, especially in reference to lawyers and other legal professionals. If that doc winds up in court, it is nothing but junk to the owner. Specifications must be written from the legal perspective, as a specification attached to a contract is a legal document, so minimum must refer to a LOWER NUMBER. Anyone with electrical knowledge will get it and ... so will the lawyers. If for any reason that is not acceptable, then drop the legaleze approach entirely and simply go for more specific and unambiguous detail as proposed by rb1957, "we recommend using a grounding cable of 0.162in diameter (#6 AWG) or larger."

RE: "We recommend using at minimum a #6 AWG grounding cable"

No "recommendation"
No "Minimum"

Note:
Ground wire:
Color Green, 6 AWG.




RE: "We recommend using at minimum a #6 AWG grounding cable"

But that would keep me from using the 2 AWG that I'd really prefer to that wimpy 6 AWG... winky smile

RE: "We recommend using at minimum a #6 AWG grounding cable"

Use 6awg or heavier (thicker?) wire.

I've seen the minimum wire size used many time.

RE: "We recommend using at minimum a #6 AWG grounding cable"

I'm with artisi, turn it round and make it clear that this is the minimum thickness.

For grounding cables we recommend the use of an #6 AWG cable or larger thickness.

"we recommend using at least a #6 AWG grounding cable"

RE: "We recommend using at minimum a #6 AWG grounding cable"

(OP)
Least has the same numerical meaning as minimum. If #6 is the least, #22 ought to be better. Thickness or heavier works.

RE: "We recommend using at minimum a #6 AWG grounding cable"

we recommend using at least a #6 AWG grounding cable up to #X AWG maximum.

What?

RE: "We recommend using at minimum a #6 AWG grounding cable"

the idea is to increase the resistance of the cable. the thicker the cable the better the resistance but it depends on the intensity you have behind, because if you have a low intensity and a heavy resistance your device doesn´t work, I suppose...For me electricity is a little bit metaphysical, I only know lights on and lights off.

luis

RE: "We recommend using at minimum a #6 AWG grounding cable"

Actually the larger cable reduces the resistance or at least increases the amount of amperage that can be carried to ground.

I'm not sure what the confusion is here. Just trying to point out how 0707's statement might be misinterpreted in a way entirely opposite of his intended meaning.

What you wrote is just incorrect. Electricity travels on the surface area of a wire. Larger solid wires have more surface area than smaller solid wires - and thus carry more electricity. So for larger loads, a larger wire must be used. The power rating of a wire is based on the surface area so a small wire will overheat and burn up when more power is carried than it can handle.

Low intensity and heavy resistance does not mean anything. "Intensity" is not an electrical term.

RE: "We recommend using at minimum a #6 AWG grounding cable"


Ohm law V=RI. The resistance of a conductor is greater the greater its length.

The resistance of a conductor is even greater the smaller the area of its cross section, that is, the thinner the conductor.

The strength of a conductor depends on the resistivity of the material from which it is made. Resistivity, in turn, depends on the temperature at which the conductor is.

I should say in my last post the thicker the cable the worse the resistance, sorry.

The former only applies to AC currents where the frequency is high enough to worry about skin effects.

Also, note that the skin effect is a function of frequency, and at 50/60 Hz for copper or aluminum wire, the skin depth is ~10 mm, so most household electrical wiring does not have deleterious effects from that problem.

RE: "We recommend using at minimum a #6 AWG grounding cable"

DC resistance of a wire is calculated from R = ρ * Length/Area, where ρ is the bulk resistivity in ohm-cm, so the larger the cross-sectional area, the LOWER the resistance.

RE: "We recommend using at minimum a #6 AWG grounding cable"

The question was posed in the form of a mousetrap. The cheese, hide behind the wire gage resistance table.
The miss understood of this thread was the lack of the wire gage resistance table.

RE: "We recommend using at minimum a #6 AWG grounding cable"

Why did a sentence wording discussion turn into a thesis on how electricity works. I blame you 0707 for writing nonsense about how grounding works when it was never asked and is off topic. You did prove how people who don't understand can misinterpret the topic sentence though. The off topic and being burned by LI on the thickness idea are making this thread suck.

RE: "We recommend using at minimum a #6 AWG grounding cable"

LionelHutz, as I told before, lights on lights off, is my background on this subject.

Apologies if it was a repeat - I was just providing my input for the whole sentence.
