Fire Resistance Rating: Fire ratings are typically denoted by "E" followed by a number (E30, E60, E90). Fire rated junction boxes are built with fire resistant material that can withstand high temperatures for extended periods. This ensures critical electrical systems like fire alarms, emergency lights, and safety equipment remain functional even in the harshest fire conditions. Testing for resistance to fi re of unprotected cable lines (cables with cable junction boxes) for use in emergency circuits.
