We had to get a dedicated plug for this spa unit as it tripped our porch frequently.  The spa had to have a new motor installed in the first month.  Spa company sent it for free but I had to become my own electrician to install it.  Good news is I now have a second career to fall back on.  Bad news...motors should not burn out in the first month!  We do live in FL  have frequent lightning storms so it could have burnt out due to a surge.
