Is this set safe for live electrical work?

Yes, it is rated for 1000V and certified to IEC 60900:2012, ASTM F1505-10 and NFPA 70E, and marked UL Classified. Always inspect the insulation before each use and replace any tool showing wear.

How does the dual-layer insulation work?

An inner layer in a contrasting color sits under the outer insulation. If the outer layer is cut or worn through, the inner color shows and tells you to replace the tool.

What sizes are in the set?

A #1 ECX driver with a 4-inch shaft, a #2 Phillips with a 4-inch shaft, and a 1/4-inch slotted driver with a 6-inch shaft.

What is an ECX driver for?

ECX tips fit combination-head screws common on electrical devices, where a Phillips or slotted driver alone can slip. The #1 size suits many terminal and device screws.

Do the handles have lanyard holes?

Yes, each handle has a lanyard hole so you can tether the tool and reduce drops that damage the insulation.

Is it a good choice over a full insulated driver set?

It covers the most common electrical fasteners and carries strong certifications, but a larger set adds Torx, Pozidriv and more slotted sizes if you need them.
