You should contact your dealer, that is what they are there for.
Thats it!! Close up shop, Gary says were no longer needed here.
A timely question as I just had my new J-345 hooked up yesterday and paid the electrician off today. He gave me a bill for $472 to do the job. My electric panel was 35 feet from where he came through the foundation and another 10 feet to the tub once he mounted the box for the shut off. Your price would depend alot on the length of the run to the tub from the box as the guage of the copper wire has to be bumped up for runs over a certain length, I think its 50 or 60 feet.The front of the tub is where the control panel is and the electric connection/panel is in the cabinet directly underneath the controls. You must take off 22 screws to get the cabinet front off and the metal box inside is where the wiring enters. There are 2 knockouts in the front sides of the base of the cabinet so you can run the wire into the cabinet through your choice of sides, or do as my electrician did and drilled a hole dirctly under the interior box, claiming the shorter the run the better. You cant see it anyway as I have a large set of steps and a platform along the whole front and simply notched it where the wire came across the front.On the 345, a 60 amp service is best as you will be able to run both pumps and the heater at the same time, a 40 or 50 amp service the heater kicks off depending on what pumps and speed you are running pump 1 on. If you opt for the 60 amp service, MAKE SURE the jumper on the circuit board is set accordingly, I cant remember the exact pins but it is listed on the inside cover of the box once you take it off, factory default setting is 50 amp.Hope this helps, post some pics when you get it up and running.
