Silly Taco Question

FredoSP

Hi All,

I feel embarrassed asking this question but here goes. I recently installed my Taco SR501 single zone switching relay with my Nest thermostat and everything is working great. I was browsing this site and was looking at other Taco installations and noticed some leave this rigid white piece of paper inside the Taco box. I remembered that my Taco came with a rigid white piece of paper inside it and removed it before I installed it. I took a picture of it, it has the numbers 9300-2944 printed in the side of it. What's the purpose of it and why do some leave it inside their Taco box and others don't? What's the point of it?

Thanks in advance.

Here's a picture of mine and another picture of one I found on the site.

It separates line voltage wiring from low voltage wiring. Probably a UL requirement.

Okay, that makes sense. I guess it's a personal preference to install it or not?

Just another NEC code requirement to make like difficult.

I think it has to do with the number of terminal connections in the control. If there are enough terminals so wire nuts are not needed inside, including adequate ground screws, the separation is not needed.

I doubt you are the only one that removes the divider

"It separates line voltage wiring from low voltage wiring. Probably a UL requirement."

It's NEC requirement that the manufacturer must follow, for liability and other reasons. What you do with the divider is your responsibility.

Thank you all for the responses.

I wrote Taco and this was the response I received:
You do not need it. It is just to show the separation of low voltage from high voltage.
