first: good group - i'm a lurker but learn a lot by reading!

i am purchasing a great hot tub from a co-worker for excellent price
(he's upgrading). i'm moving it saturday to the back patio of my
townhome, i'm sure everyone envys that job.

i have an electrician coming saturday evening, and am going to request
he use the 220 power in the laundry room to hardwire the hot tub to.
(my dryer is gas, so i don't use it), and the fuse box has two switches
strictly for the dryer.

the basement outlet is right next to the patio, so pretty close,

but a hot tub dealer mention the outlet might be 30amp, and the hot tub
is 50amp

should i be concerned about this? and is it a correctable problem, and
at approx. what price?

thanks in advance, i appreciate it!
