Frequently Asked Questions

If there is no neutral wire in the wall box, can I use the ground wire?

A10, 120 VAC, 300W, Single Inductive Wall Mounted Dimmer Swi...
No. This is a violation of the National Electric Code. The ground wire is part of the safety system and is not intended to be a return path for electricity. If no neutral wire exists, and there is no alternative device that can be used, contact a licensed electrician to have a new neutral wire run to the box. (See PCC Tech Tip #1 for more information.) Yes but not in the same way as the older X-10 devices work.

Why does the switch require a neutral wire in the electrical wall box?

PowerSURE Residential Power Failure Safety Lighting Frequent...
The neutral wire allows the circuitry internal to the PowerSURE Safety Light to connect to a complete 120V AC circuit for proper operation. If there no neutral wire is available, the safety light will behave as if there is a power failure. The LED light will stay on when it is dark until the batteries are exhausted. It will still work as a standard switch.

THERE IS NO GROUND WIRE IN THE BOX, WHAT DO I DO WITH THE GREEN WIRE?

Lutron Electronics, Inc.
When no grounding means exists within the wallbox, the 2002 NEC article 404.9 exception to (b) permits a dimmer without a ground connection to be installed as a replacement. For this type of installation, cap or remove the dimmer ground wire. A dimmer installed under this exception must be provided with a plastic, noncombustible wallplate (all Lutron plastic wallplates meet these requirements).

What is a neutral wire, and how do I know if I have one?

PowerSURE Residential Power Failure Safety Lighting Frequent...
Warning: You should consult a qualified electrician familiar with all the local codes and ordinances when working with electricity. Before planning to install a PowerSURE Safety Light, you should turn off the electricity to the switch that you want to replace. Remove the wall plate cover and use a flashlight to look at the wires in the wall box. If you can't see them, then you may have to pull the switch out far enough to see them.

What gauge speaker wire should I use in my system?

Amplifier Frequently Asked Questions
For the best speaker damping and least amount of power loss you will want to use the heaviest gauge that is practical. The length of the speaker wire should be considered when considering wire gauge. The shorter the run, the smaller gauge you can use with minimum power and damping factor loss. The longer the run, the heavier gauge you will need to minimize power and damping factor loss. You will also want to consider the size of power amplifier you are using.

How do I wire the output for unbalanced use?

Technical Support
Since this unit uses a cross-coupled output, it is imperative that pin 3 be grounded to pin 1 and the audio positive connected to pin 2. It is also very important to make sure the unit is earth grounded using a separate wire connected to the chassis ground screw near the red power connector. See Sound System Interconnection for further details. Not having an earth ground connection to the chassis is the number one cause of failure

What ground tackle do you use?

Atom Voyages | Frequently Asked Questions (FAQ)
well as matching your ground tackle to the size of your boat, you need to match it to your windlass (or lack of windlass), the strength of your back, the exposure and depth and bottom conditions of the anchorages you may frequent and your anchoring technique. Unless you know you will always anchor in shallow well-protected waters with good holding ground, you'll need serious ground tackle. Though I've anchored in waters as deep as 65 feet, that's extremely rare.

To what should the ground wire be connected ?

Techno Screen FAQ
Connect the ground wire to any metal part of the CPU or any metallic object around the CPU (like filing cabinet).

Is a 400 Amp Posilok a wall box?

TMB FAQ
No. The Cam-Lok Posi-Lok is a sequentially interlocking single-pole connector system. Posi-Lok output and input panels can be, and sometimes are, mounted in "Wall Boxes".

What is Neutral Henna?

Henna for Hair - Frequently Asked Questions
Neutral henna, a green powder that smells like freshly cut grass, is neither henna nor neutral. It is Cassia obovata. Cassia obovata contains anthraquinones, particuarly Chrysophanic acid, a remarkable anti-fungal, anti-microbial and anti-bacterial. Cassia obovata doesn't color hair. It will help damaged hair, make hair full, glossy, healthy.

What type of wire can I use to connect the remotes?

Technical Support
For runs up to 200 feet any five conductor wire, 22 gauge or larger, will suffice. Use shielded wire for distances greater than 200 feet.

c. Is it true the ground wire is RED?

MUSTANGS MAILING LIST FAQ: PART 3, Version 1.1
Yes, the RED wire is identified as the "amplifier return wire" and is terminated with a screw to the metal dash frame. It is the system ground. Locations for the Mach 460 are as follows. There are two mid/high speakers up from right where the mirrors are (inside of the car). They are triangular in shape and fit very nicely and discretely. The next two pairs are at the doors, and these are mid/subs just like the rear ones, which are located on the rear deck.

How do I tell which is the hot wire and which is the neutral in a table lamp?

ONLY CONNECT LLC - SPECIALIZING IN SMALL ELECTRICAL PROJECTS...
The Plug: On newer table lamps, the prongs on the plug are different sizes. The larger prong is (should be) the neutral. The receptacle in the wall has different sized slots; the longer slot is (should be) the neutral. For safety, the plug should fit in only one way. The cord: If you rub your fingers along the two sides of the cord, one should be smooth while the other has little ridges. The ridges are (should be) on the neutral wire side.

What method do you use to secure the tipi cover to the ground?

Frequently Asked Tipi Questions (FAQ)
We use the same system that the Indians used to secure their tipi covers - pebble ties. To best explain how this is done, I'll quote from my father's book, "The 20th Century Indian Tipi" During those early days, we experimented with metal grommets and with web loops to attach tie downs around the bottom of the cover. We found that grommets eventually cut through the fabric and consider them to be unsuitable for tipis. Almost all tipi makers agree, and avoid the use of grommets.

Can I use an in-wall keypad to control music?

Kaleidescape - FAQ (Frequently Asked Questions)
Yes, you can use an in-wall keypad to control music. This is useful for listening zones that have no video display and no touch panel. Kaleidescape's very simple keypad interface includes button presets for playing specific albums, mix albums, artists, genres, collections, including User-defined Music Collections. You can cycle through any collection by using next and previous buttons, and you can press-and-hold a button to set it to the now playing list.

When I am testing do I test from hot to neutral or ground?

FAQ's - Modular/Manufactured Homes
Testing of Modular/Manufactured Homes should be done from hot and neutral to ground. Please refer to our Modular/Manufactured Homes resource page for more information.

What is a ground plane? Can I just attach a ground wire to a mag mount antenna?

Frequently Asked Questions
A very important distinction! A ground plane is REQUIRED for a mag mount antenna to work properly. For optimim performance, a ground plane for 800 MHz is a minimum 28" x 28" plane of metal that becomes an integral part of the mag mount antenna. A ground plane is NOT a ground wire. Or put another way, a ground wire will NOT satisfy the need for a ground plane. Ground plane information also here.

What is a multi-ganged electrical wall box?

PowerSURE Residential Power Failure Safety Lighting Frequent...
When you see more then one wall switch or receptacle installed side-by-side in the same wall box and covered with a single wall plate, the wall box is a multi-ganged electrical wall box. Multi-ganged boxes can be found in many locations in a home, usually near entry doorways.
