Hello sparkies
I have stopped by because i have a slight problem in my house.
I am a master plumber, I have worked with you guys for years,
I hope you would be so kind as to steer me in the right direction.
when my AC kicks on, my lights blink.
From what I know, that aint good.
I have a 200 amp service so that is not the problem
any guesses as to wth is up?

Is the wiring to the A.C sized correcrly? sounds like you may have a Volt drop problem in your House
 
yes sir, it is a big --- orange wire. 10/3 if i remember correctly the unit is a 3 ton unit
" A big --- Orange Wire 10/3" can't seem to find that a cable of that description in the Regs Book!!! Don't think many Electricians over in the UK will be familiar with it either.
 
What size motor is on your AC and how is it controlled IE powered direct (DOL) to bring it on instantly or speed controlled to ramp it up?... it is not unusual for the inrush of a motor DOL to cause local flickering although we do have regulation over here about this and adding transients to the network which may effect other uses.

It is quite possible your local distribution Network feeding your property is already heavily loaded thus making the inrush of your A/C show up annoying side effect, if this is the case there are options to suppress this but not really cheap.

This is all assuming the previous suggestions of a loose common point in the system is not the cause.

Frodo have you check your connections yet. I have a 3 ton unit myself and my lights don’t flickers it’s not a big load. I suspect that your problem is in your main panel
