Vague manufacturer info

Looking to get power to a vehicle storage lift in an attached garage.

The spec sheet says “115V 20 amp 1Ph” for the power requirements.

from the panel with a new circuit involves running approximately 115’ through 3 sections of finished basement. 2 areas drop ceiling, one 12’ space drywall ceiling then into the garage and 20’ of 700 Wiremold.

I have an existing 120 V receptacle within 3’ of where the power pack plugs into.

That circuit currently has around 7 amps of load on it.

I do know it’s a 1HP motor but don’t know any other specs. Equipment is not on site but owner would like it ready when the installers come.

It operates a small hydraulic pump that turns the gear box.

In the past I’ve used Mfgr info stating the need for a dedicated circuit only to find a minimal amp draw once the equipment arrived.

Thoughts on how to handle this
 
What's the current for a 1 HP, 120 VOLT motor? If it exceeds 50% of 20 amps then the fastened in place equipment cannot be on the circuit with other receptacles supplying not fastened in place loads. {210.23(A)(2)}

That’s what I’m attempting to find out. Seems nowadays smaller motors don’t follow what we would know as traditional specs. I called the Mfgr and mentioned the nameplate data and they were baffled as to what I meant.

Take for instance using a SqD slide chart for motor amps doesn’t correspond with an electric power washer motor or an air compressor motor I have in the garage.

What sort of load is the 7 amps? Is it likely to be used while the lift is in operation?

The current load is a 3.2A refrigerator, a 1.7A beverage cooler and a couple amps of misc battery charging equipment.

No definite usage time for the lift. Once the car is up and in storage it could be months before it comes down.

If it's a true 1 HP then it cannot be on a 20 amp circuit shared with the other cord and pug equipment.
 
Here is the info I got from the Mfgr on the motor I was questioning.
Duty- Int.
Volt-115
Amp-20
PH-1
HZ-60
HP -2.5
Thermal protection- None

It’s a pre assembled cord and plug connected unit with a NEMA 5-20 male end.

Would this need to be a 30 amp circuit with thermal protection to operate it properly?
