I'm wiring a new pool at a single family residence. I'm planning on adding a subpanel near the equipment which will be on the side of the house exposed to the weather.

1. The pump is a 230V 1.5 HP, Variable Speed, .4 - 5.6 Amps

Breaker - I figured it to be - 1.5 HP = 10 x 2.50 = 25 Amps (430.248, 430.52)
Conductors - 1.5 HP = 10 x 1.25 =12.5 Amps 15 Amps - 14 AWG (430.248, 430.22A)

The owner wants to cord and plug connect the pump. How can I do this? I don't believe there is a 25 Amp, 240V receptacle. Would I be better off just hard-wiring it, since the panel will be only 10' away?

2. Since the subpanel will be mounted outside the residence and not in a separate structure, I won't need to drive a ground rod, correct?

3. The pool is located 4' 6" from the side of the house which has aluminum siding. I believe I have to bond this, is it as simple as installing a lug and hitting it with a #8 to the pool bond?

Thanks,
 
The 25A breaker is generally the max size allowed. You don't have to go that big. With a 5.6A nameplate and 10A in the book, a 15A breaker would probably hold as would a 20A. A pool pump starts quickly and has little initial load.

So I'd put in a 20A circuit on #12 wire, an L6-20 receptacle, and a 2 pole GFCI breaker.

Correct - no ground electrode system required for a subpanel in the same building.

Aluminum siding probably needs to be bonded. I don't know how to do that effectively (don't know how it is interconneted). But you'd start by bringing the #8 from the equipontial grid to it.
 
Is the 4' 6" measured from the inside edge of the pool? Is so then you will need to bond the siding and also have an equipotential bonding around the perimeter of the pool.

I agree 20 amp gfci breaker is fine
 
Yes, the measurement was taken from the inside edge of the pool. Any suggestions on how to bond the siding properly?
