First 3 phase board change - tips appreciated

Morning all, hope your having a good weekend

Ok, the boss wants me to do my first 3 phase board change tomorrow, and would like to get as many tips as possible to make the change go smoothly

Its a 36 way board, approx 6 SWA cables to be terminated with a few t&e, most circuits are single phase, with just a few 3 phase circuits for machinery

How do you do your 3 phase boards and how do you keep them neat and tidy ?

Thanks all
