Ideally, you'd never work on a live electrical circuit, but isolating the power sometimes just isn't possible. In which case, the metal spanners and sockets in your toolbox need to stay there, as the risk of short-circuit or electrocution is just too high.
Thankfully, our Insulated Sockets & Spanners are just what you need. They're built to the same high standard as our other tools, but they're coated in plastic so you can't come into contact with live terminals. All are tested and certified to a safe voltage level. Check out these products if you need to work on live distribution boards, batteries, rectifiers or generators.
