pool sub panel 219 feet, 100 amp

[Stevenfyeager]

Pool person says he needs a 100 amp panel, distance is 219' On the on line calculator I read AL 2/0 to get 3 % drop. Am I correct ? Thank you. 3 % is necessary ?

What's the actual load?

Voltage drop percentage is not required by the NEC. It's only a fine print note and they are not code, nor enforceable.

I don't know, the pool man just asked me for a 100 amp panel. He did say the heater is gas .

Well then you'll need to decide what number you will use in the VD calculation. When it comes down to the actual load it is possible that 40 or 50 amps will give you the 3% VD you're looking for. If he'll pay for 100 amps of load in the calculation then go with that.

If it’s gas your loads going to be small! Get specs there like hvac guys they don’t really know what they need

One thing to consider about voltage job is the actual voltage you're starting with.

If you start with 240v, a 3% drop will leave you with 232.8

If you start with 245v (very common) then a 5% drop leaves you with 232.75

Don't go for a set percentage, go for a percentage which leaves you with good voltage after drop

That’s all well and good, but there’s no way in H-E-double hockey sticks the actual load is anyway near 100A.

I know
Just using 100a to compare to his 100a figure

If it's a basic pool no way it's even close. But last year we did a pool.equipment room that used every bit of %80 load on a 400 amp 3 phase sub panel. 12 pumps, 60 lights(yes 60 lights), fog machines, underwater speakers, slide from spa down to pool, etc, cabana, bubblers, firebowls,waterfall, pond, For a house.

Is that an amusement park or a pinball machine?

Just a run of the mill backyard pool

Some people just have too much money. Personal opinion, of course. Then again, they are keeping it in circulation.

If the pool person wants 100 amps give it to him and charge for it.

 

[ptonsparky]

If the owner can afford the pool 250' from the house, he can afford the 100 amp. I would be inclined to go with a full size Cu EG as well.

Exactly. I wired a brand new house a couple of years ago with the most basic pool. It was just a pump, filter and one light

And they didn't need anything more than a 20 amp mwbc

Pool installer wanted a 100 amp panel. Homeowner said put whatever the pool guy wanted

Okie dokie
100 amps it is

A heater/chiller sale is going to be far easier in 2-3/yrs if the 100A sub-panel is already in place. If the customer has to swallow another $3k in electrical costs to get an $8k piece of equipment, they're more likely to say no.
