Second-Class Electrician Skills Test Practice Set This is a practice set (DK55, etc.) for the Second-Class Electrician Skills Test. Please understand that these are used items. The reference book is old, but it was sufficient for the exam. This set was purchased and used for the practical exam preparation for the first half of the 2024 Second-Class Electrician exam. Since some of the exam content changed in 2024, there is a shortage of outlets with grounding, but I practiced with regular outlets. The breaker is chipped, but there is no problem for practice. I bought extra small ring sleeves, so there are plenty. The rubber bushings have cuts in them. The tools are a stripper, crimper, pass-grade multi-tool, and pass-grade clips. [Regarding the wires] I used them sparingly, so there are quite a few left. You might need to buy a little more 2c1.6 wire.
