You can use all programs at free of Cost.Section General — BC We respectfully request a code interpretation regarding the location of automatic transfer switch serving an optional standby system supplied by a natural gas fired generator within an R-3 occupancy residence.

Section This residence does not have any required emergency power equipment and it does not fall within any of the criteria as described within Section Yes, where there is no required emergency or Standby loads, ATSs that serve optional standby are allowed to share the main service room with service equipment.

The controller provides output power and control to 24VDC lighting, shades, and door hardware. Control of lighting and shades is either by a network connection or by means of momentary 24VDC switches rated for 24VDC, which are connected to the controller. Note that all wiring is Class 2 and the lighting fixtures are UL listed. Could the continuous, uninterrupted metallic conduits containing telephone cables pass through electrical closets?

Yes, where such communication conduit is installed in accordance with subsection Article Would this requirement also apply to panelboards that are recessed into a wall where the access to the space above the panelboard is not generally not accessible?

Requirement of subsection Does the code require another 20A receptacle in the closet per F, in addition to the two receptacles provided for the washer and dryer? Section Subsection My question, who determines the habitability of areas of the basement? We are adding one receptacle in a bedroom. The existing circuit that we will tapping off is not AFCI protected.

Are we required to have AFCI protection for the entire circuit? Habitability is determined by the Certificate of Occupancy and the construction document as filed and approved by the Department of Buildings.

For the purpose of the electrical code, the above is acceptable.Model Railway Electrics Make Easy. Don't be put off by the main title. It's not the circuits that are short, it's the articles. This series of articles on model railway electrics was originally intended to be published in a monthly newsletter with the intention of giving an insight as to the many simple ways to get the most operational fun from your train set or if you take things a bit more seriously, model railway layout.

The articles and associated diagrams are intended to demonstrate practical and inexpensive explanations to many of the electrical control situations encountered when designing the control system and wiring for your layout. Of course this subject of model railway electrics has already been well documented in many commercially published books but these books all have one thing in common, they tend to very quickly become complex and full of a lot of inane and unnecessary technical theory and jargon.

Electrical Notes

Be assured, this will not happen here. This may seem at first to be an odd question but there is a convention that has been used for more than sixty years concerning this very subject. Model railway manufacturers the world over have all adhered to this convention resulting in when you put your train on the track and turn on the controller, the train will proceed in one consistent direction.

The convention states that when the furthest away rail is more positive than the nearest rail, the train moves to your left. Reversing the controller makes the furthest away rail more negative than the nearer rail, therefore the train moves to the right.

If your train does not adhere to this convention, you have a faulty train. This error could be due to a number of reasons. If the loco is brand new then there is a manufacturing fault and it should be returned to the retailer as being not fit for purpose. However, on older pre owned models, common reasons are that the magnet has become reversed or that the wiring to the motor has been reconnected incorrectly.

If directionally controlled headlights are installed, it is important to ascertain whether the headlights and travel direction are in synchronisation.

Reversing the wiring to the motor or lighting will remedy the problem. Why is direction important? You really want all your trains to run the correct way for ease of operation in running, shunting and is of course it is absolutely essential for double heading or banking purposes.

Also, as we shall see later in the Short Circuits series, control circuits utilising diodes will not work as intended on reverse wired locos. Don't end up going backwards. It's easy and it's worthwhile to get your direction correct.

When connecting the two power leads to the track, the most convenient way to do this is by means of a power connector or power clip. It is recommended that an analogue type is used as this contains a suppressor intended to reduce any interference to other wireless type apparatus. A power clip for use with digital systems does not contain this suppressor as it would corrupt the digital command signals. Almost everyone who has a model railway has a mains powered electrical device to make their trains run.

They may refer to this device as a transformer, a controller, a line controller, a throttle or even a power unit. Whilst all these terms are generally accepted, there is really a little bit more to it than that. These devices consist fundamentally of five essential and discrete components within the box. These components are, a transformer, a rectifier, a user variable speed setting device, a direction switch and an overload protection device.

There are two principal types of unit, ones with variable current control and ones with variable voltage control. Both types are in common usage today. A third, less common type of unit is also available called a Feedback Controller. These are not recommended for use with certain types of electric motors used in locomotives.Also, the same wiring circuit diagram can be used for 2-way lighting or controlling electrical appliances from two different places by using two-way switches.

Below is old-school staircase wiring circuit diagram. Here we can control a bulb from two different places by using two 2-way switches. Consider the above 2-way switch wiring diagram which has been used to control a bulb in staircase. The schematic shows that circuit is completed and bulb is ON.

To switch ON the bulb again, just switch ON the same switch at upper portion of staircase. Obviously; you can perform the same operation from the bottom switches installed in staircase.

For this purpose, consider the figure given above. In this case, you can see that circuit is complete and bulb is ON. Suppose you want to OFF the bulb from the lower switch at bottom of stair.

You can switch ON the bulb again to switch ON the same switch installed at the bottom or downstairs as shown in the fig. It is the new 2-way switching connection method which can be used for staircase wiring as well as it is efficient as compared to the old-school method where 2 wires are used instead of three wires.

The current position of two way switching connection using three wires circuit is ON and the bulb is glowing. The circuit operation is same as mentioned in the above figures but the connection method is different as the first terminals of both switches are connected to the live Phase wire. The second terminals of both switches are connected to the bulb to provide live line supply while the Neutral is directly connected to the bulb as common wiring method.

This basic circuit is little confusing as by looking in it, it makes a short circuit to the same wire which is not harm in this case when both switches are ON or OFF which is making a loop to disconnect the live supply to the bulb, Hence, bulb will not glow in that case. This is not always the case, but in some cases like shared flats and long stairs, we may control the light point in staircase wiring from three different places by using two 2-way switches and an intermediate switch as shown in fig below.

Hello sir I am Tarun wason from bhiwani Haryana. I an looking for electrical job i am completed diploma in electrical engineering. I am very work harder i give best in my work so please give me job. You should do a few likely to ascertain wherever you should have these individuals previous to purchasing that.

The Diagrams are great, very informative. I just wanted to may be help clarify something with you. The switches in your diagrams are not 2way switches. There are 3 possible directions for current to go. If you go to get one from a parts store the box will also say 3 way switch.

Hope this helps.Click on the above to visit our featured advertisers. Tell them you saw their ad on Wiring for DCC! Welcome to the website that coined the phrase "DCC Friendly!

This is the most popular section of this web page! If you are a manufacturer, talk to your DCC customers. Consider making DCC friendly turnouts - I tell you how below. Modelers, write your favorite manufacturer. Tell them you would like DCC friendly turnouts. To see a schematic of a turnout wired to trackwork, see the trackwork section of this web page, suggestion Check out George T.

Engineering - Relay Logic Circuits Part 1 (E.J. Daigle)

Galyon's HO Turnout Compendium. George discusses all sorts of details about installing the industry's most popular turnouts. The compendium is in. You will need Adobe's Acrobat Reader. These diagrams "say" it better than words!

In the above diagrams I have also included how you would power route the frog. See the appropriate section below for your favorite switch. Power routing of the frog, and using a light bulb for short circuit protection, is optional. See section below for more on power routing. I show jumpers called bonds between the point rails and closure rails. I personally like turnouts that have the point rail and closure rail that are one piece and therefore eliminates the need for bonds.

Commercial turnouts that have point rails hinged to the closure rails, may eventually need a bond if they develop poor electrical connection at the hinge. You are wise to put the bond in now as the hinge could become a hot spot should a short occur. However, if you are using a DCC friendly turnout, the likelihood of a short developing is much less!Wiring your Philippine house.

Philippine electrical wiring. As part of our project to build our house in the Philippines, we had to learn about Philippine residential electrical systems. As with our other writings, we do our best to chronicle our missteps as well as our successes, so that our readers get slice of reality about coming to the Philippines and building a house, not a fairy tale. Our pole-mounted meter.

From the standpoint of electrical engineering theory, the Philippine system is similar to that used in the U. From the utility pole to the residence panel box we have one or two load wires and neutral conductor. We have a ground earth provided by the homeowner.

Looking at how things were done when we built our Philippine house may help other considering house building in the Philippines to get an idea how things are done here. One final note. The Philippine electricians we have met have been quite professional. Wage rates are negotiable and far more reasonable than in your home country.

We hope this essay will be of help in making you a more knowledgeable home builder. First, some background. This from Schneider Electric helps explain the purpose and nature of each of the three conductors. This simple model is appropriate for DC systems but does not work for an AC system because the flow of the power is continually reversing direction with a frequency of 50 or 60 times per second.

From the point of view of the equipment or the power source, the source and return wires are constantly being interchanged. In fact, no equipment can tell which wire is which! It is easily demonstrated that the two power wires to any piece of AC equipment can be interchanged without any effect on function. In fact, in Europe [and the Philippines], the plug on a piece of equipment can be plugged in either way! Therefore it is connected directly to the grounding third wire.

In essence, then, two of the three wires at the wall receptacle are actually grounded wires, one being used for power flow, and the other connected only to exposed metal parts on the equipment.Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
