Cities usually have codes for using certain types of conduits, so be sure you talk with your local building department before making your hot tub purchase. You want to make sure you have not only enough room for your hot tub, but also enough room away from your home according to your city's building code. Many codes require at least five feet of clearance between your home and your property line.
Once you've met all the codes and have your layout plan figured out, be sure to call Metro Electric. What most suppliers won't tell you, is that the electricians they refer you to are NOT licensed with the state of Michigan. Don't leave yourself liable, and call the pro's at Metro Electric for your hot tub installation.
Most pumps will require an extra hard-wired circuit, one that's entirely dedicated to the electrical on the tub. A 240V, 50-amp GFCI (Ground Fault Circuit Interrupter) should be sufficient on many tubs. Multiple-pump tubs may require a 60-amp circuit. Metro Electric can wire your hot tub from your electrical panel OR a GFCI specifically for your hot tub.
