Excuse me if this is the wrong place to ask the question.
I was wondering if anyone could help me out.
I don’t have a lot of knowledge when it comes to electrical work, especially in terms of electrical rules and regulations or codes.
My question is mainly related to large scale industrial/commercial buildings for a bus way service entrance.
I have been told that any electrical entrance (such as a bus way service entrance) that pierces through a wall from outside to inside a building must be insulated. I can’t find any Ontario code or regulation to confirm this.
If this is the case, does that mean the hole/entrance in the wall can be insulated with something as simple as, for example, a Ruxol™ material, or is there any specific insulation required for this?
