ETL listed

If I may ask, what does it mean? Should all tubs have this listing? Please forgive my ignorance.

Not all tubs have an ETL listing.

Every tub should have a listing with a similair company like UL or Warnock Hersey or ETL. There may be more companies like this that I am not aware of.

These companies are certifying the safety of these electronic appliances.

You will find one of these companies stamps of approval on almost anything electrical.

ETL is a testing laboratory. They are similar to "UL" or "Underwriters Laboratories."

UL created a standard for safety for portable hot tubs, and ETL and UL both use that standard to test for things such as:

• Max Temperature
• Electrical safety
• Bonding of equipment
• suction safety
• control system safety - and more

If you are getting a permit for your wiring, you will want to be sure you have selected a spa which is ETL or UL listed. Building inspectors know both - and to make it easier, ETL listed spas have a sticker:
