Fluorescent Lighting?

[dwellselectric]

Question is it true that the nutral carrys more on a fluorescent lighting load as opposed to in incandescent lighting load? and if so why?

 

[infinity]

What kind of system are we talking about? A WYE system may have a larger neutral current due to harmonic loading caused by the ballasts. A single phase system wouldn't have harmonic currents.

 

[dwellselectric]

So say on a normal single phase residential load the nutral wouldn't carry extra load right?

Yes. That is correct if fed from a single phase 120/240 volt system.

That is what I thought but my boss is telling me that I am wrong

Ask your boss where he is getting his information from and have him explain to you what he's thinking. Maybe you guys are on two different pages.

hmm perhaps i will ask him he is just so thick headed he is never wrong

If that were true, you could never power fluorescents from a GFCI-protected circuit.

If he's so confident in his answer send him to this forum for a debate. There are many here who will disagree with him.

Shhhh! We don't want to scary him away.

you are all so good at it

you are all so good at it

But you cant scare me. I think what your boss is talking about is he or someone he knows has been hit off the neutral side of a flourescent ballast. So you are talking about not only the surprise of getting hit with a supposedly grounded conductor combined with the reactive voltage of the winding when opened and closed through your boss I presume will really hammer you. Open circuit voltage is about 600 volts I think .

hmm reminds me of a guy i worked for, told me that we could use 10-2 on a dryer and 6-2 on a range because the house was in the country and it didnt require an inspection. thats the day i quit,btw he is no longer in bussiness.

We need our own TV show "Electric Myth Busters", I sometimes cringe when I work with other electric contractors and listen to the things their men tell me. I politely try to explain why they are wrong and sometimes I am able to teach them something, but often they want to argue or tell me I am crazy. I have been told and your the expert JEEZEE...and they walk away.


Examples:

Neutrals hurt worse than hot conductors.
A transformer will not work if it is not grounded.
Electric systems need electrodes to operate.
BYO is NEC mandated and it is a violation to use YBO and vice a versus.
GFP are people protectors.
20 amp OCPs trip at 20 amp.
A neutral is the same as an Equipment grounding conductor so using it as such is no problem.
And IGs, I don't want to even start. Who ever came up with this was trying to torture electricians. The inventative ways I have seen IG's installed one could write a book.
Electric testing companies are all crooks, testing is stupid a waste of time, we do nothing but turn knobs and anyone can do that (WHICH IS TRUE).

I think this could actually be a great idea for local contractor/IAEI meetings.
Would you mind if I started a thread for good ideas? Or maybe you could start the thread.
I have approximately 22,000 photos I have taken (I actually have taken over 100,000 photos in the last 6 years and have downloaded, saved, filed and labeled the 22K photos), some of good work, some of not so good work. A lot of these photos and other info could be used.
This week along was a slow photo week, and I took approximately 600 pics - this week I concentrated on Utility photos.

These photos are so important to me, that I have spent untold hours/days/weeks/months (working sometimes into the wee hours of the morning) putting them in files and backing them up in multiple locations for safe keeping.

You forgot one big country rule. You can run a 120-v light from a 220-v well pump by using one side of the line and the bear ground wire as a neutral. I guess some of those guys are still living. Semper Fi.

ya know it sounds funny but ive actually seen that. one that sticks out in my mind, they had 1 240v circuit for the whole house water heater, dryer, a big window air unit, then they pulled the microwave off one side. it was a totoal mess, you could either run the air, dry clothes but not wash them cause the water heater would kick on or take a shower. to make maters worse yet the whole thing was #12 on a 30a fuse. wound up rewireing the whole house. thats a real nice supprise when you just buy a house!

BTW what does this have to do with lightning?

It seems that Lighting and Lightning are interchangeable. The spell check said it was OK.

Maybe we need a section on Lighting to keep this section on Lightning?
