The meter installers wore the lower voltage yellow gloves, and they were tested monthly and dated and only usable for up to a month after testing also.
Many moons ago, I wired in a live feed of 240 to a big fuse box I installed, while it was live in a big industrial building. I took several precautions, including tools with insulated grips, and standing on a thick dry rubber mat, while wearing shoes with dry rubber soles. And if course, not touching the metal of the box or building.
Recently I put two outdoor ground fault outlets in a friend's house. Even though I knew the circuit breaker was off, I sat on a dry insulating mat, ( the foam rubber rool up army sleeping pad I have ), folded to be 2 layers thick.
Every additiinal layer of safety you can have is a good idea.
