I already posted that my new Hayward pump had a "blade" style plug instead of the twist lock.
So, I was going to replace the plug end as advised. When I cut it off, I realized that the new pump's cord is 16 AWG wire. (The pump is a 1.5 HP, 12 amp; the receptacle is 20amp; the OLD pump was also a Hayward -- but it had 12 AWG wire.)
A) 16 AWG is too small to power a 12 amp pump, right?
Extra credit) Why the **** is Hayward selling pumps with 16 AWG wire?!?
B) Can I just attach the OLD cord to the new pump? (Old pump was 11 amp; new pump is 12 amp)
