Spa emergency shut off switch

[Mr. Inspector]

Does any one know know why an exception is here for residential spas in the International Swimming Pool and Spa Code, while The IRC requires does Emergency a shut off switch for spas?:

2015 ISPSC 313.7 Emergency shutoff switch. An emergency shutoff switch shall be provided to disconnect power to recirculation and jet system pumps and air blowers. Emergency shutoff switches shall be: provided with access; located within sight of the pool or spa; and located not less than 5 feet (1524 mm) horizontally from the inside walls of the pool or spa.
Exception: Onground storable pools, permanent inground residential swimming pools, residential spas and residential water features

2015 IRC E4208.4 Emergency switch for spas and hot tubs. A clearly labeled emergency shutoff or control switch for the purpose of stopping the motor(s) that provides power to the recirculation system and jet system shall be installed at a point that is readily accessible to the users, adjacent to and within sight of the spa or hot tub and not less than 5 feet (1524 mm) away from the spa or hot tub. This requirement shall not apply to single-family dwellings.

So I guess you go by the strickest?

I would think this to mean only the single family meets the exception, not other residential occupancies.

 

[Mr. Inspector]

But then the IRC does requires an emergency shutoff switch

This ought to be an interesting discussion....What does the NEC consider as a "single family dwelling"? Remember that the IRC covers One and Two Family Dwellings and Townhouses.....

NEC definition
Dwelling, One-Family. A building that consists solely of one dwelling unit.

ISPSC definition
RESIDENTIAL. For purposes of this code, residential
applies to detached one- and two-family dwellings and townhouses
not more than three stories in height.

 

[Mr. Inspector]

emergency shutoff switch for a spa:

IRC requires it for all detached one- and two-family dwellings and townhouses not more than three stories in height.

ISPSI does not require it for detached one- and two-family dwellings and townhouses not more than three stories in height.

NEC does not require it for a single family dwellings but does require it for two family dwellings and town houses.

Think "safety" first and then "do as you would".

 

[SCBO1]

My 2012IRC, E4208.4 last sentence sez: This requirement shall not apply to single-family dwellings.

This leads me to believe that TWO-family dwellings require an ESO.

 

[ADAguy]

Never know what the other family may be doing, has or hasn't done with the spa.

They rarely share a yard or spa.

 

[ADAguy]

maybe yes, maybe no.
