If you’ve spent any amount of time on our services pages, you’ve probably noticed us consistently mention dedicated circuitry. You need it for your outlets, for heavy appliances; gosh, you even need one for your microwave. But what is a circuit, and how many do you really need? Important questions, and luckily for you, our certified electricians have answers.

Contact Kolb any time you need electrical services!

Put super basically, a circuit is an engineered circular path that electricity takes to do work. Think about the light switches in your home. When you flick them on, electricity flows into the closed circuit that sends power to your fixtures and bulbs, and voila! You’ve got light. All electronics and electrical applications work off of the concept of circuits.

A circuit always starts and stops in the same place, creating a revolving door of sorts for harnessed electricity.

So, What Is a Dedicated Circuit?

Technically speaking, a dedicated circuit is no different from a regular circuit in application. It is simply set aside to power one, specific appliance , tool, or piece of equipment. Dedicated circuits are required by NEC (National Electric Code) for all major appliances (generally those that involve massive, fluctuating voltages). So what about portable tools that eat power? Your electric drills, and hair dryers? This is why outlets are on dedicated circuits, too!

The answer here is a little malleable. It depends on a number of variables including:

Notice that all of these variables can change, or be changed. That means the number of circuits you need equates to basically this: As many as it takes. If it has a switch, uses a motor, or gets plugged in, odds are it needs a circuit (maybe not a dedicated one, but a circuit). But how do you find out exactly how many you need? Well, that’s what electricians are for! One thing you can find out on your own, is if you have too few circuits.

If you experience any of these complications, you probably need more circuits, or an upgrade:

There are more complications than this, but they can get complicated, and often have other causes as well.

Did you know the lighting in your office could be making you feel sick?

Feeling unmotivated and lethargic, suffering from headaches or eyestrain? There are some simple steps you can take to energize the work environment to combat stress and elevate mood by choosing the best lamp for your desk or task lighting needs. 

Healthful illumination is key to an environment partnered with increased productivity and job satisfaction.  The trend today is to improve upon what you already have rather than investing in new construction.  Upgrading your office with affordable and energy-efficient lighting is an investment that leads to outstanding visual improvements and a more healthful work environment.

Smoke alarms are your first line of defense in the event of a fire.  Smoke alarms come in two main different types.  Ionization and photoelectric.

Ionization smoke alarms have a ionization chamber inside the smoke alarm unit itself.  The smoke alarm chamber consist of two plates about a centimeter apart.  One of the plates is charged positive by the battery or transformer in AC models and the other plates is negative.  Alpha particles constantly released by the americium knock electrons off of the atoms in the air, ionizing the oxygen and nitrogen atoms in the chamber. The positively-charged oxygen and nitrogen atoms are attracted to the negative plate and the electrons are attracted to the positive plate, generating a minuet, constant electrical current. Upon smoke entering the chamber, the smoke particles attach to the ions and neutralize them, so they do not reach the plate. The drop in current between the plates triggers the alarm.

Photoelectric smoke alarms have an internal chamber with a light beam.  When smoke enters the chamber it blocks the light from entering the photoelectric sensor causing an alarm to sound.  Smoke may also cause the light beam to scatter creating an inconsistent pattern on the photocell causing the smoke alarm to sound.  Photoelectric chambers can detect a smoldering fire faster than most ionization type smoke alarms.

Smoke alarms are most commonly seen as battery operated units in older homes.  Battery units are also common in situations were a smoke alarm is added and AC power is not accessible.  AC units power the smoke alarm with standard AC current from the homes wiring.  AC units are common in newer homes.  Current new construction code requires smoke alarms to be AC with a battery built into the unit as a back up power source.

Current smoke alarms used in new construction homes are AC and battery combination units as stated above.  They also require a dual sensing smoke alarm unit.  The most common dual sensing combination is either photoelectric and ionization or a combination ionization and carbon monoxide unit.

Carbon monoxide also called the invisible killer, is odorless and colorless gas.  Carbon monoxide is most commonly created in the home when unburnt or improperly vented heating equipment releases the gas.  Carbon monoxide can be created from natural gas heaters, wood burners, and oil burners.  Carbon monoxide can also enter the home from the exhaust of a running vehicle or generator.

Carbon monoxide effect some people easier than others.  People such as elderly, pregnant women, infants, and people with emphysema, asthma, or heart disease can suffer the effects of carbon monoxide much quicker than a healthy person.

We can install most major brands of smoke alarms.  We offer smoke alarm installation for Kiddie and First Alert.  In addition to Kiddie and First alert, we also offer smoke alarm installation for USI, and BRK smoke alarms.  We offer smoke alarm installation for AC units with batter backup, AC only units, and battery only units.  We highly recommended the AC with battery backup units for superior performance.  We also offer smoke alarm installation for interconnected units.  This type is highly recommended.  They function as following:  When one smoke alarm unit goes into alarm mode it causes the other smoke alarms to sound an alarm.  If access limits being able to connect the smoke alarm units we offer a wireless type smoke alarm installation to insure the units are properly interconnected.
