HELLO

[frodo6]

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?

 

[frodo6]

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.

10/3 wire. orange wire.

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

How are doing today Pete

 

[frodo6]

YES I did. I jut checked it a few minutes ago. a loose connection on the breaker screw

Thanks guys. I hate freaking wires
30 years ago, I was laying under a kitchen sink {new Construction} hooking it up and the wire to the disposal zapped my ear . I jumped up and chased that damn sparky all over the house and into the yard. we became good friends after that

Have you turned the air conditioning on yet to verify it’s fixed

10/3 wire. orange wire.

yous should fit in well here. we even make allowances for plumbers. over here we call them wet-pants or water clowns...... no offence meant.

Oh so so, thanks for asking.

Glad you fixed it, not a loose Fire Nut then?

That's why we do thorough testing over here!

The US sparks do testing Mate "Bang Testing" can't get more thorough than that, either works or it don't, simples really.

DPG are you saying that we don’t do no kind of testing. We are not that reckless and if I wire something or do service calls I guarantee you that I know without a doubt there will be no problems. I know what I’m doing do you

I have been doing electrical work for 32 years and don’t insult my intelligence, we do have our share of dumb asses just like y’all

Yeah we certainly have our fair share Mw, although and I'm not including your good self, most of the YOUTUBE VIDS of US electricians, don't appear to have any test instruments in their tool kits, as well as not appearing to do any actual testing, you knoe hook it up and switch on scenario, could this be that only the DAs you speak of publish YOUTUBE VIDS?? or, I suppose it's a case of the few spoiling the reputations and competences of the many, which I hope fervently is the later case.

I'm only going on what people, including yourself, have said about testing (particularly a thread about lack of earth loop impedance testing) and also views on there being no instances of loose connections causing fires.

And of course the OP's new build wiring can't have had a thorough inspection & test.

We ground everything and just how hard can that be. The USA is a lot more simple than the UK when it’s grounded it’s grounded and I stand by my work if you think we don’t know what we’re doing come on over and show us how
