I'm using BCBC2018, 9.32.3.5.(3) Principal Ventilation System Exhaust Fan, requires an dedicated and labeled on/off switch.
I've just requested a switch for an HRV with a plug in cord and got the "we never did that before".
The electrician suggest pulling on the cord if quick shut off is needed.
The functials statements for the switch are the followings:
F81 To minimize the risk of malfunction, interference, damage, tampering, lack of use or misuse
OH1.1 – inadequate indoor air quality
OH1.2 – inadequate thermal comfort
OH1.3 – contact with moisture
OP2.3 – damage to or deterioration of building elements
I originly thought the switch was for safety in case of malfunction (sparks flying out, electrical cord red hot and melting etc). therefore pulling on the cord wouldn't be an acceptable means of shutting it down in an emergency. Now, I have doubts. It seems the functional statements are not related to safety but to the integrity of conditioned space.
In addition, the electrician is recalling a building official asking for on/off switches on the plug-in of on-demand water vessels. Apperently BC safety authority, having jurisdiction over electrical trades, has rules [unofficially?] that it was not required.
Curious to have other BO's thoughts and XP on this.
Thank you
