Hot tub wiring, done by someone licensed

Everyone else ranking for this is paid when you say yes. Here's when you shouldn't.

• You are about to have other electrical work done anyway. Pulling the spa circuit as a separate visit months later costs more than folding it into a job that already has an electrician on site with the panel open.
• The panel is at its limit and the service upgrade dwarfs the spa. That is a legitimate reason to choose a smaller plug-in spa instead, or to postpone. It is not a reason to squeeze the spa onto a panel that cannot carry it.
• You have not decided on the final spa position. The supply is installed to a location. Moving the spa two metres after the wiring is buried means digging it up. Settle the position first.
• You are tempted to reuse an unknown existing circuit to save money. An old circuit of unknown origin, protection and condition is the worst possible foundation for a spa. Anything reused must be verified, and verification often costs more than a new run.
• Nobody will permit or inspect it because it is "just a spa". If an electrician offers to skip the paperwork, that is the signal to get a different electrician — not a saving.
• The spa is a temporary or inflatable one you will pack away in autumn. Those are designed to run from an ordinary protected outlet. Installing a permanent hard-wired supply for something seasonal is money spent on the wrong problem.

This is the part of a hot tub installation that can kill someone. A spa places people, wet and barefoot, in electrically conductive water beside a high-current appliance. A wiring fault that would be a nuisance indoors is a fatal one here. Every element described on this page — circuit, ground-fault protection, disconnect, bonding — exists because people have died without them. Have this work done by a licensed electrician and inspected. Do not treat a video as an instruction manual.

• Are you licensed for this work in my jurisdiction, and will you pull the permit?

  Both parts matter. A licence without a permit still leaves you with unrecorded work that an inspector never saw and an insurer may ask about.

• Have you calculated whether my service can carry the spa, or just checked for free breaker spaces?

  These are different checks and only one of them is the right one. An answer that describes a calculation is a good sign.

• Where will the disconnect go, and can I reach it from outside the spa?

  It exists for an emergency. Stand in the spot and ask yourself whether you could reach it while wet, in a hurry, without leaning over the water.

• What metal near the spa will you bond, and what did you find when you looked?

  The best single filter question on this page. An electrician who has surveyed your railings, fence, gas line and concrete will answer specifically. One who has not will answer vaguely.

• Is the ground-fault device dedicated to the spa, and how do I test it?

  You should leave the job knowing how to test protection yourself and how often the manufacturer says to do it.

• What certificate or inspection record will I be given at the end?

  Keep it with the spa paperwork. It is the document that answers questions from an inspector, an insurer, a future buyer and any engineer who services the spa later.

• If the protection trips after you leave, what is the process?

  Establish upfront whether return visits for a tripping circuit are covered and whether diagnosis is chargeable. Intermittent tripping is common enough to plan for.
