What is equivalent to WP-1 motor rating?
(OP)
Hi:
Received a motor spec requiring WP-1 (weather-protected-1).
These are to go on Water Treatment Plant flocculators, and are for outside service.
Since WP-1 does not exist for small motors under 100hp, I need to find the closest common specification off-the-shelf for these 3 and 5 hp units. WP-1 is an ODP motor, surprisingly.
Are we talking IP54, 55, or washdown duty here?
Thanks,

May be "WP" is meaning "weatherproof" and this is an improvised version of TEFC to protect the live parts from ingress of water, rain, snow, airborne and other providing an additional protection and giving the outer surface a special coat of painting to protect against unfavorable weather conditions. It corresponds to IP55 [at least]. See:
