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.
Rotary hammers pull current and can dim lights. Some vacuum cleaners trip 15 amp breakers too. If that's the only indication along with the lack of receptacles, I see no issues. I would check with the city about installing the new service or panel. I understand NY can be rough on stuff like this. Good luck.
