You can if you wish use them but the proper way to work with AC is NOT TO WORK WITH THE POWER applied WHILE THE FINGERS or other appendages ARE IN ANY WAY GOING TO TOUCH IT. Not just a switch or circuit breaker, for this sort of work you unplug it physically and box the plug.
Nice thing about rubber gloves that are not properly cared for is that the AC will find a way to kill you with them on. And the same applies to a wooden pole, a fiberglass pole and to your utility truck. Which can happen if you touch it without carefully walking around it to make sure your *now dead* buddy didn't DROP A POWER LINE ON IT!!! < why? Two or more people on one project means not just the guilty moron DIES.
Consider NOT using them until you have more than a basic understanding of AC safety. A mistake is too permanent though you will be crunchy and good with ketchup that is not good for you. But you'll be a delicacy to dragons that don't like to cook.
I had a nice spiffy guide, deleted it for incompleteness. There's just too much information you need to be safe. Look at the library for books on this. It's not hard to learn enough to be safe but it does take effort. Ask a librarian about looking up books on basic safety when working with electricity and the basic skills for doing normal home electric work.
would you reccomend wearing thick rubber gloves? or will u get electricute any way?
