P.S. The issue of Flicker Factor could be brought up here!
There's a Thread on ECN which briefly covers this and includes a link to an IEEE document about Flicker Factor.
The last Residential Service Design I did which was around April, 2000 - new 400 amp 1 phase service as part of a Remodel / Addition - after meeting with SCE's Design EE, She gave me their design plan and it included Flicker Factor (4.6% with 2 50 amp 240 VAC HVAC units driven by a 12KV x 120/240 VAC 1 ph 3 wire 25 KVA 2.0%Z Transformer, Service Feeders = 4/0 AL).
