hello, i'm wondering if i am in need of a service upgrade. i recently bought a house, in NYC and i knew walking in that the electrical panel was a little dated. i was ok with that cause i've worked for three years with IbEW local #3 in ny, and i figured that i can change the panel on my own but. My Problem is that due to the fact that the house is in need of an upgrade, there is a shortage of outlets in every room. and last night the cable guy plugged in a hilti rotory drill in the an outlet and everytime he used it i noticed that my lights would dim. i'm wondering if this an indication of a service upgrade or a load reduction of my circuit panel.
