When it comes to replacing a main breaker in your home, it may feel like an overwhelming and expensive task, and you likely want to be sure that is your only option before you move forward to schedule the electrical services. Finding an electrician you can trust can help you to decide whether main breaker replacement is your best option, but you may also want to learn the basics yourself so you can make an informed decision on your own.

Let’s take a look at the basics of circuit breakers and the main breaker, how they work, and when you would need to consider replacing a main breaker:

Circuit breakers exist to keep the home’s wiring from getting overheated or catching on fire. The necessary size of the breaker for a home depends on the wiring size as well as the expected electricity load that it will support. When the circuit breakers are in a closed position, they conduct electricity. However, when the flow of electricity (measured in amps) goes beyond what the breaker can handle, it trips or opens. This activity “breaks” the circuit and stops the energy from flowing.

You can reset the circuit breaker by closing it, but repeated tripping and the need to reset the circuit over and over can wear down the breaker, which can end up reducing its capacity.

The main breaker is the circuit breaker that serves as a safety feature to protect your electrical panel from overload. Overloading can then lead to overheating, which is obviously a fire hazard. This breaker is usually located at the top of the smaller circuit breakers in the electrical panel. Some main breakers are locked in place, while others snap or slide in. The main breaker serves to turn on and off power that is incoming to the home. Without a well-working main breaker, you will likely have major power problems, and it may even shutdown altogether.

While sometimes your main breaker will fail without any warning, you will usually have signs that point to it wearing down. Here are the typical warning signs that will clue you into something being wrong:

If you are noticing several of the signs above, it’s time for a main breaker replacement. If you are only experiencing one or two symptoms, you may just need some repairs. However, in either case, you need to call a professional electrician for an appointment immediately. An expert will be able to assess the situation and determine exactly what is going on and provide you with a plan of action to get your electrical services running smoothly and safely once again.

2. Ghosts in the yard.

If you have handy lights lining a path or driveway at your house, this idea will take no time at all. You just need to collect a bunch of old plastic milk jugs with the tops cut off or white paper bags (I suggest making the decision after you get the weather report for All Hallows’ Eve). Simply draw eyes on the jugs/bags with a black marker, and slip them one by one over each Image via MarthaStewart.com

Here’s an ultra affordable Halloween lighting project, if your preferred poison is the frightening beyond of unexplained extraterrestrial phenomena. Just fill your house (or yard) full of anchored helium balloons containing green glow sticks. Add faces with traditional alien eyes or something even more creative! If you really want to play it up, you and your family could dress up like extraterrestrials and pretend the real you has been abducted.

4. Mini mummies.

If you prefer cute décor over the more macabre, a quick project to make mini mummy candles holders only requires a jar or glass cup, some white gauze, and some googly eyes. Simply scrunch up the gauze around the jar to look like the mummy’s linen wrappings. Add the eyes, and ta-da, you’ve got a precious little mummy come back to life with candlelight. They’re a crowd pleaser, trust me.

constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.
