The Flexel Green bus-bar insulation disk (1000) is an accessory for underfloor heating systems designed to insulate electrical connections within the system, specifically the busbar, and is typically available in a pack of 1000 units. The "Green" in the product name likely refers to the color of the disk itself and the retailer's "Eco Friendly Heating" brand, rather than an application with a green/yellow earthing busbar (which is usually a different product)
