Speaking of connections. I had a remodell today and got into the panel. Always give them a good looking over. The main lugs had never been tightend. House was build in the 70's . One lug I put atleast 6 turns on . The other lug looked fine but the threads had seized. This is approx a 1500 square foot house with AC. By alrights it should have gone out by now. But visually looks ok. No signs of burn . To top it off before they installed breakers the mudder was kind enough to texture the inside of the panel.
Back on topic take this house for example. Someone correct me on this if I'm wrong going from memory. Lets do some math.
1500 sq foot home @ 3 VA =4500VA
first 3000va @ 100% 1500@35% = 525 VA
Total VA for house 3525VA
Range 8000VA
Dryer 5000VA
AC 5000VA
----------------------------
total VA 21,525
21,525 VA/240V = 89 Amps
So whats wrong with a 125Amp or 150Amp service. 125Amp service is a typical installation around here for me. We'll put on a 200Amp if there is a possibility of a hot tub or something in the future.
My question may still come out false.
