Ceiling Fan Wiring

Ceiling fan wiring is meant to provide power connection to the fan. If done with proper care it's safe and easy. The ceiling fan wiring is divided into two parts:

1. Wiring from fan terminal box (if provided) to internal motor or circuitry and 2. Wiring from switch box or switch unit up to the ceiling fan. The first part of ceiling fan wiring falls under the fan maker's scope and the rest is taken care of by the user. This part may be put inside a concealed unit called concealed wiring. The wire from the switch box comes through this concealed unit up to the fan terminal box. There are usually three types of ceiling Fan wires: 1. Power wire, or phase wire, or hot wire. 2. Neutral and 3. The ground or earth.

Color Code: At the time of ceiling fan wiring, a defined Color code helps to identify the types of wires. For the hot wire or the power wire, different color combination such as black or red are used depending upon the industry standard, whereas generally white color is used for ground wires.

Gauge: For the purpose of ceiling fan wiring, proper gauge of wire is to be used. Though gauge usually varies with the current rating of the equipment, no. 12 or no. 14 is to be used for such wiring. No. 14 is the smallest permitted ceiling fan wiring under most codes.

Proper copper multistranded wires are used for ceiling fan wiring. The ends of the wire must be dressed properly and crimped with a crimping tool. These steps are followed in order to rule out connectivity problems. However, Ceiling fan wiring varies with the instructions of the manual provided by different brands.

Safety: *Before giving final connection, power in the loop should be switched off either tripping the MCB or circuit breaker. A neon tester can be used to check if the power is off. In case of any doubt, remove the main fuse or trip the main breaker. However, removing the main fuse or tripping the main breaker will shut off the power to the entire house. *Wherever two wires are joined externally, proper insulation with insulation tape is to be put for safety. *Continuity of ceiling fan wiring is to be checked with a proper continuity tester device before giving power. Proper connectivity of these wires with terminal box and switches also to be checked.

Electric Horseman Are Getting Attention

 Another flyer came in my mailbox yesterday about a horse show. After quickly glancing at it, I threw it in the pile of magazines and "stuff" to be read at a later date.

I'm sure the content was carefully thought out to provide the information about the show classes and the printer spent time balancing the copy so that it was pleasing to the eye. It was printed on quality stock and had a mailing label neatly attached. It was mailed well in advance of the show date.

I spent little time looking at it because it was in living black and white and was just, yawn, boring. Don't misunderstand, printed black and white promotional material conveys the message adequately, if you can get my attention to read it.

Get my attention. That is a challenge for all people in business today. How do we get our customers' and prospects' attention?

Don't try to sell using "The Adventures of Ozzie & Harriet" programming when the customer expects "Desperate Housewives".

Try putting some wow in your marketing for your: lesson program, training clinics, horses for sale, summer riding camp, horse show, Pony Club event by using an electronic approach. Gather e-mail addresses and start a newsletter like this one to stay in contact with your group. Add photos of last year's event to your horse show flyer. We love to see our pictures. Add links to your newsletter to your website for more information.

Remember that black and white flyer on my pile? If that flyer had come to me electronically, I would have been able to click on links to:

a website to see photos of the past event
read more information about the show including testimonials of past show participants
see a photo of the stabling available
mapquest to see how far away the show is
see availability for overnight lodging
read about the food available at the show and about the best place for dinner that serves tired, slightly horsey smelling diners
download an entry form in pdf format
have someone call me or answer a question via e-mail
read a list of vendors at the show
know who the farrier and vet on call are
You get the idea. Going electronic with your business marketing will give your business or event the excitement it needs to stand out from the hypnotic effect of black and white printed marketing. If you are trying to attract customers with Ozzie Nelson's three page manual on marketing maybe it's time to create a new buzz with colored fonts, e-mailed announcements, color photographs, a website with more information.

How can I help? Shout, call or e-mail me. Just DON'T write me a letter. Neither of us has time for that any more.

Some Do's and Don'ts When Hiring An Electrician / Electrical Contractor

Selecting the right electrical contractor isn't as easy as picking someone out of the Yellow Pages. The ramifications of hiring the wrong contractor can be financially disastrous and even dangerous.

First and foremost, it's imperative to know if the contractor you're considering hiring, is licensed, bonded, and has adequate general liability and workers compensation insurance.

Then, you need to determine if they are experienced in the type of work you need performed, and if they are generally considered good, honest and reputable.

The best place to start answering some of these questions is at the Board of Examiners of Electrical Contractors and / or the Division of Consumer Affairs (basically the Authority having Jurisdiction), and of course, the Better Business Bureau.

Now lets pretend for a moment that you have an electrical job you need done. Not an emergency -- perhaps it's just fixing a light that stopped working. What would you do

Would you call a few contractors and get multiple bids You can, but I wouldnt necessarily suggest it.

Most people think that they should get multiple bids for every job. This isnt the case, and in actuality, putting to bid every little job may in fact backfire.

Good contractors are few and far in between, and asking for multiple bids for a small job will only alienate them the next time around. Try looking at this from their point of view. Their time is worth probably about $100/ hr, and yet, he or she makes the time to come to your residence and provide you with a free estimate for whatever work you may need.

Typically, a good contractor will try to provide you with an extra-competitive bid, especially the first time around, just to make you a customer.

But how can you tell if the first contractor walking into your house is The good contractor Some simple rules may apply here, but remember there also are exceptions to every rule.

 A good contractor will typically look the part. In other words, if he or she looks messy and disorganized, then it's probably indicative of the type of work he or she does. Someone who takes pride in their work usually takes pride in their appearance. Some contractors may argue this point, but remember we're talking generalities here and not the exceptions. He or she should have some type of company identification (even a shirt with a logo would do).

 A good contractor will have company cards with their company name and / or their name, telephone and license # on it.

 A good contractor will respond to your calls quickly and provide you with a free estimate (for most jobs) the same day or within a reasonable amount of time, and will take the time to explain what they will do and how they will do it.

 A good contractor will never offer to do the job without taking out permits and may even walk away from a job if the homeowner insists on not taking them. Remember, permits are additional insurance for the homeowner guaranteeing (through inspection) that the job was performed safely and correctly.

 A good contractor will never cut corners and do something unsafe in order to accommodate your budget. They will, instead, offer suggestions on how to modify your plans to meet both their code and safety requirements, and your budget. If these two cannot meet, then they will wish you good luck and walk away from the job.

 A good contractor will be happy to provide you with copies of their insurance certificates and references when asked. Try not asking for them unless it's a decent size job.

Suppose a homeowner would like to make a minor alteration or addition to their electrical system. If the electrical system is old, then that part of the system may need to be brought up to current code standards before they can add to it or modify it.

In order to circumvent this regulation, the homeowner may insist that the job be done without permits and possibly even hire someone unlicensed to do the work.

What he or she doesn't realize is that if their house burns down, they will very likely NOT be covered. Your homeowners policy probably states (very clearly) that anyone doing work on the residence has to be properly licensed and all building, plumbing and electrical codes must be followed, and work performed with permits wherever required.

If you hired someone whom you thought was licensed, but ultimately wasn't, it still may NOT be covered because you didn't take out permits for the work, and as far as the insurance company is concerned, it was done illegally.

If and when you decide to put a job out to bid, make sure that the work is properly specified (in minute detail) so that all the contractors are bidding on exactly the same things. Otherwise, there's no way of telling who's bidding apples and who is bidding oranges. Not properly specifying a job is probably the most common mistake homeowners make.

Why Let's assume you need to have 10 receptacles, 4 lights and 2 dimmers installed in a room. Without specifying the exact types such as (Standard, Decora, other), amperage (15/20), location and method of use (this is used by good contractors to determine how many receptacles to put on a single circuit), types of lights, bulbs (R30, R40, halogens, etc.) and trims (for Hi Hats) standard, eyeballs, etc., wattage of bulbs (determines type and rating of dimmers used), there is no way of telling who is bidding what. And these are just some of the variables used for a fairly simple job!

 A good contractor always uses first-class, contractor-grade materials and never uses anything else, regardless of budget. They will usually price and give you the higher grade items automatically. This is where they get in trouble when bidding with other contractors. Someone else may be using approved but inferior materials, which would enable them to come in considerably lower than the good contractor. They probably know that you'll have problems with the items installed sooner rather than later, but don't care because it falls beyond their warrantee period (if they even have one).

 A good contractor will take into consideration how the receptacles are being used (such as computers, entertainment equipment, vacuum cleaner, etc.) and automatically factor in (price) dedicated lines for these items, even though current codes may allow all of the receptacles to be wired on a single circuit.

Other contractors won't, and will therefore be able to do the job cheaper. Of course, when you start tripping breakers because the new receptacles are overloading the circuit, there won't be anything to do about it, because it didn't violate any codes at the time, and more importantly, you didn't specify it.

But how could you specify it You're not in the electrical field, and you assumed the contractor would know better and factor this in.

Well, you're right. The good contractor already factored it in, but you gave the job to the other one.

Are you starting to get the picture about the dangers of multiple bids Very often, you don't end up with the good contractor.

That's a pretty typical bidding scenario, and its obvious why people are intimidated dealing with contractors. Make the wrong move and it can spell big trouble.

Anyway, if you do bid the work, try to have it properly specified perhaps by an architect or engineer. A good rule of thumb would be, if you get multiple bids, always pick from the middle up, and never, ever pick the lowest bid.

When you've finally selected a contractor, ask them for a copy of their insurance policies, and make sure everything (including start and end dates on larger jobs) is in writing.

Very often smaller contractors work out of their own house or garage, and many do not carry workers compensation insurance. This may or may not be a factor. If they have a helper with them or send someone else to your house to do the work, it becomes a huge factor.

Without this insurance policy, you (the homeowner) are 100 % liable for any accidents their workers may incur. Additionally, many contractors have only enough general liability insurance to satisfy state regulations, but nowhere near enough to pay for your house if it burns down.

Finally, a last note of caution; as with everything else in life, you get what you pay for ".

In other words, don't let price alone be the determining factor when hiring an electrical contractor. Remember, if a plumber messes up, youll have a flood, if an electrical contractor messes up youll have a fire or perhaps even worse.

Good Luck.
