Conventional wisdom is to wait until after lvl 5 before dipping into wizard so you have Extra Attack. Personally, I waited until after I got War Magic (lvl 7) to add them. I wanted to be able to booming blade+attack. Really you can wait until whenever you want and makes sense story wise. Some build add them much later, like after lvl 14-15. So i'd say its kind of campaign specific, as to when to wizard-dip (if you do at all).
There is a solid argument to dip at lvl 2, since the early levels tend to go much faster if you really want to cast spells right away. A lot kind of depends on if you're starting at lvl 1 or at a higher level, how long your campaign will run, if you're rolling stats or point buy and even the total composition of the group can influence your decision.
I personally dipped 2-wizard levels so I could get the Arcane specialization feature and arcane recovery. (I went abjuration- the arcane ward is like bonus HP than can refresh! But there are lots of options)
But Neogod22 is right, if you only splash 1 level of Wizard, it really opens up a lot of options and you don't especially need more than that.
The most I've seen added was 5 levels of wizard- anything more than that and someone probably has a different concept in mind entirely.
