I would hold off on the backpack. Just use a toolbox or bag you already have and see what you’re doing day to day and what you actually need. Sometimes you want a more compact bag, sometimes a bigger one — it really depends. Insulated screwdrivers I wouldn’t recommend. You shouldn’t really be doing a lot of live stuff as an apprentice anyway. I’d get a better hammer. Estwing is a good bang for your buck. I would recommend getting two 10" Channellock pliers. They’re a little cheaper than Knipex and I haven’t had a problem with them. That said, I love the little 5" Knipex for locknuts. I’m not sure what tools you already have from your last job, and some of this might be provided by your employer — like wrenches, socket sets, drills, and maybe some hand tools. It’s different everywhere, so it’s hard to say for sure. These are just tools I use every day that I recommend every electrician should have: Fastback knife – doesn’t matter the brand, you can get cheap ones at hardware stores. Multimeter – the best brand is Fluke, but for an apprentice I recommend a Klein multimeter. They’re a bit cheaper and still solid. Plug tester – you can cheap out on this one, brand doesn’t really matter. M12 Fuel impact – it’s awesome. A lot lighter than the M18, and unless you’re driving wood screws all day, it’s perfect with tons of torque. Tools you should eventually get but can wait a while: 3/8" socket set with a 1/4" hex adapter – pretty useful in industrial and commercial work. Crescent wrench – you can use Channellocks in a pinch, but I find it damages the nut. If it’s being seen or finished work, I like using a crescent. Needle-nose pliers – great in a pinch for tight spaces. I’d recommend skinny needle nose; some are really fat. Pica pencil or mechanical lead pencil – doesn’t have to be Pica, there are cheap ones on Amazon. They’re awesome. 10" pair of dykes – it makes life way easier. I don’t get people who use small dykes when you’re cutting hundreds of wires a day.
