is it; 29000w, 40 horse power@ 240V
protected by 125A cir brker through set of #1 copper


what you think????????

Thank you

depends on many things
capacity in lbs/passengers
speed
type: geared, traction, hydraulic

rough numbers
lift is ~ 20' assuming first floor is btm landing
avg cap 6000 lb
speed 150-200 fpm
hydraulic 15-20 hp
geared twice as much
I doubt a traction for this application

are you saying it IS 40 hp 240/3?
or asking the estimated HP?

40 hp ~ 104 x 125% = 130 A #1 (ignoring V drop)
150 cb
if a certified pnl it should have a nameplate

for sizing of conductors;
FLA x 140%
Right???

per Table 430.22(E), yes.

look at art 620
feeder to the controller?
or from controller to motor?
