What do you tell your customer

[texie]

Can't really blame the electrician, how many times have you had a customer buy huge light fixtures after the house is already wired? I have seen chandeliers that took a 15 or 20 amp circuit by theirselves. If this is just a bunch of 120 watt fixtures, then maybe some blame can be shared. Can the customer change some or all to cfl or led? That will reduce the load greatly.

Given the very low power factor of some of the cheap CFL's out there, it may not lower the current enough to solve the problem. Has the labled wattage of the lamps on the circuit been compared to the meter readings to be sure there is not another unknown load on the circuit?
Situations like this just serve to illustrate the sad state of professionalism in the residential market.
