I need a 40 cal/cm² arc flash suit for live work on 13.8 kV switchgear in an indoor substation. Focus on comfort and full-body protection is a plus. What brand or specific suits do you recommmend for this level of protection?

I can't recommend but do a web search, due diligence etc. Be sure it complies with either ASTM or IEC standards. See where it is made, some counterfeit PPE is out there.

In another thread, Deerfoot Casino was mentioned when online platforms in Canada were discussed. The overall impression was simplicity and accessibility, which made the reference feel authentic. It wasn’t the central theme of the exchange, just a side remark, but the anchor added credibility. That subtle detail improved the overall tone and highlighted how even minor mentions can contribute to trust in community discussions.
