ohm's law sucks.

missed a 120 volt receptacle on a bid.

30' up in the air, feeding a wifi repeater.
7 amp load.

Seven Amps for a WiFI repeater?
Sounds a lot.

Did we ever hear what size wire the plans call for? Most jobs I've bid tell you the wire size somewhere.

[ptonsparky]

I was just awarded a job. The plans may be complete next week.

Other than for fire pumps and maybe a couple of other things the NEC does not have voltage drop limitations.

But local code may. The Florida building code limits voltage drop throughout the state for example.

What is their limit?

[Strathead]

What is their limit?

3% for branch circuits, 2% for feeders. It used to be in chapter 13, but I think it just cahnged in the 2010 code adopted in April.

the prints will call for two #6 and #8 ground.

i haven't drawn them yet.

it was my shortfall, i didn't realize the repeaters would pull that much.
i was figuring a nominal 180 watts per device, a quad would give 360 watts, or three amps.

i am now the proud owner of six rolls of #6 simpull, and three rolls of #8 green simpull.
$2,200 or so.

next time, i'll clarify something like that.... 'eh, it's only THREE OUTLETS, not even something to consider.... ;-)

If this is a 20 amp circuit and conductor size is increased to #6 for voltage drop purposes then the equipment grounding conductor also needs to be increased to #6.

If this is a 60 amp circuit using 6 AWG conductors - the equipment grounding conductor can be 10 AWG.

Just doesn't quite sound right does it? But that is what code says.

A code compliant way to use the 10 AWG EGC is to run a feeder to near the outlet with 10AWG EGC. Then run shorter 20 amp branch circuit to the outlet with smaller conductors.

I disagree. The EGC only has to be increased in size proportionately when the ungrounded conductors are upsized, not to the same size as the ungrounded conductors. See 250.122(B)

Well I thought that is what I was explaining
