Last week I had the Electrical Inspector at my house to check on the central air conditioning which I had installed at the end of last summer. While he was there, I took the opportunity to review with him my plans for adding a sub panel for my shop to my existing service.
My plan is to use the old load center left over from my house prior to renovations. This already has a 100 amp main breaker and all I have to do is separate the neutral and the ground in this box. I also explained to him that I would be adding a 100 amp double breaker to my main box. My main box has 40 breaker slots (about 3/4s occupied) and I indicated that I would put the new breakers near the bottom, just below the 50 amp double breakers for the central air.
The inspector said to me that I might consider moving the higher amp breakers to the top of the box. That would minimize the lights dimming when these loads came on. My lights do dim a little when the A/C first starts up.
My questions then to the learned members of this group:
1. Do you agree that moving of the hi-load breakers to the top of the box will really minimize the lights dimming when their loads come on?
2. If true then I will move some existing breakers. To do so, I will have to extend the black wire on some 15 and 20 amp breakers. Are crimp-on splices acceptable for this?
