what article would an Electric forklift charger fall under?

[ctaylo360860]

AT first I thought that it would fall under article 625, but after reading into it, it looks like this is an off-road vehicle and not under article 625.
would i need to follow Article 422 under appliances?
here is the beast I'm trying to wire up.

Info on my appliance

 

[ctaylo360860]

I'm thinking that 422.10 (A) would apply for my conductors 41.9x1.25 since it would be considered a continuous load would be 52.38amps. looks like i would need to run # 6 copper.
as far as my ocpd would i be using 422.11 (E)(3)?
422.11(e)(3) single non motor operated appliance states overcurrent can not exceed 150 percent of the appliance rated current if the overcurrent protection ration is not marked and the appliance is rated over 13.3 amperes. where 150 percent of the appliance rating does not correspond to a standard overcurrent device ampere rating, the next higher standard shall be permitted.
41.9x 1.50 = 62.85
if i wanted it looks like i could run a 70A max ocpd. I plan on using a 60amp ocpd since i have one found already.

IF anyone sees something i may have missed please point it out! thanks in advance.

I also planned on setting a Qo260nats near the charger so it can be shut off in case of emergency or if it needs serviced.

I don't recall there are any special rules for forklift battery chargers.

Appliance. Utilization equipment, generally other than industrial,
that is normally built in standardized sizes or types and is
installed or connected as a unit to perform one or more functions
such as clothes washing, air-conditioning, food mixing,
deep frying, and so forth. (CMP-17)

I am not sure that a forklift battery charger qualifies as an appliance, based on the code definition.

I don't think it is a continuous load, but it won't hurt anything if you treat it as one.

Yeah I really couldn’t find anything in the nec on it.
I thought it should be treated as one since it will be charging lift equipment I believe 11 hours or overnight.

Is this because as the battery gets charged it the lomaximum load will not last 3 hrs?

Make sure you put in a disconnect that can locked

Yrah the qo260nat in post three should have a spot to llock the breaker out.

Most battery chargers taper off as the battery becomes charged I think it is highly unlikely that a forklift battery charger would run full bore for more than 3 hours, but I suppose there are some chargers that might. Most lead acid batteries prefer to be tapered off anyway, so I suspect that's the way most chargers work.

I added the wrong spec picture. Damn charts

If I’m looking at the name plate it doesn’t line up with the spec chart correctly.
The unit says 43 and the chart says 45.38

Looks like I could get away with 50a cb and 8cu phase conductors then? Or how do I size my conductors and ocpd?

I should be able to use a little 60a pull out disconnect as long as it’s lockable. I’m guessing it will be cheaper and easier to find
