The larger the hot tub the more power and electrical current that is needed. When you go up to three or four pumps for hot tubs you may be looking at a 40-amp feed. We also do hot tubs for areas where you unable to get that level of power to it. These are called plug and play hot tubs and they are 13 amp. You can plug it into an outdoor waterproof socket and your hot tub will run perfectly. You can still have the massage jets and music and lights on and don’t need to invest in the cable required or need an electrician to come out.
