The ratchet internals are super fine as well as smooth. It is well insulated with zero risk of shock at the voltages I use it with. The ball detent connect and release system is superb as it holds tightly with no wabble or free play at the connection. I am not an electrician per say, I just use it while doing maintenance on my home 200 amp/240 volt power panel. I use it in conjunction with the 6 inch insulated extension bar that I purchased with it. They both work well and would recommend the product for such SAFE use. Harry-O
