My customer has had a bad run of luck with contractors with his new basketball training facilty .
This time its the way the HVAC system was installed
First off they used the wrong wire type since everything is pen and exposed in this facility it has to be physically protected . so NMC- Romex is not permitted
So that's first error they made. 2nd they never installed an outside disconnect on condenser unit so it can be safely serviced.
Plus to make it more dangerous they brought the plastic jacketed romex out to condenser thru the metal building with no sleeve to protect it and the wire is not rated for outside use.
Then although your allowed to use PVC to vent the high efficiency furnace. Your not allowed in this facility it has to be metal exhaust pipe and metal drains . due to fire spread from PVC as its a high occupancy place.
The contractor is a total slob residential guy obviously never did commercial work because he would know better .
Needless to say the owner is very upset and contacted the company to get it corrected.
If not next call will be building inspector.
