Perhaps you've always wondered what's in the mysterious metal box on the basement wall. It's a circuit breaker box, and without it your whole home electric system would be unsafe, leaving you in danger.

Circuit box repairs or upgrades require an expert, but you don't need to be a master electrician to understand the basics of how it functions. The most common problem is a tripped circuit, and you can usually reset it yourself.

What's in the Box?

The circuit box is frequently found in the basement, although it could also be in a garage, closet, utility room or even outside. All the electricity coming into your house flows through the box.

If you open the metal door, you see a bank of switches. Each one corresponds roughly to a room in the house, while certain outlets for major appliances like the washer or furnace probably have their own switch. They should be labeled.

There also may be a main disconnect breaker, usually at the top of the box, which allows you to cut off power to the entire house. In many newer homes the main disconnect may be outside near the electric meter. Some homes do not even have one. This is useful if you are doing electrical work in your house, or in the circuit box itself. The switch should be labeled “main” or something similar.

How It Works

Why do you need a circuit box? When an electrical device malfunctions, such as the motor in your freezer overheating, wires can get crossed, creating a huge spike in electric charge. That puts you at risk of overloading your electrical system, and unchecked overloads can cause lead excess heat stress on wires, or worse.

Fortunately, your circuit breakers are on the job. There is an electromagnet or bimetallic strip inside each breaker. If the current moving through the circuit gets too high the device flips a switch, disconnecting the circuit. No more electricity can flow to the part of your home where the problem is, so the danger is averted.

So if the power goes off in one part of your house but still works in the rest, a tripped circuit breaker is the most likely culprit. The switches in your electrical panel should be labeled; if not you can still tell which one got tripped, because it will be flipped part way toward the off position. Some switches also show red when they've been tripped.

How Do I Fix It?

All you have to do to restore power is flip the switch all the way to the off position, then back to on. If flipping the circuit back on doesn't solve the problem, it might be something more serious. In that case, it's time to call a licensed electrician.

Some newer circuit breakers have advanced features, such as the ability to detect when a person makes contact with a live wire and automatically cut off the current, potentially preventing injury or death by electrocution.

If you live in an older home you may still have a fuse box. It operates on the same principle as a circuit box, with one major difference -- the wire inside the fuse actually burns up if too much current passes through it, so if the fuse blows, you need to replace it. Most fuse-style panel are maxed out, so if you have one it would be a good idea to consult your electrician and see if it’s time to consider a replacement.

Homeowners insurance is an often-overlooked but significant cost in owning a home. Your insurance policy protects you against major losses in the event of a disaster, but you need to invest in premiums each month, which can be tricky for any family on a budget. However, you do have a measure of control. Your home electrical work in particular plays a big role in calculating your insurance payments, because outdated or faulty wiring can increase the risk of a fire. Read on to learn about what types of wiring can drive up insurance rates and how you can mitigate the costs.

The Insurance Company Makes the Call

If you don't know what kind of wiring you have in your house, you should have an electrician evaluate your system as soon as possible. Since the risk of bad wiring is so catastrophic, it might be hard to even insure a house that is too far out of date. “Some insurers will not insure you at all, some will require an inspection, and some will classify you as high-risk,” CEO of insurance-services company InsurEye Alexey Saltykov told the Financial Post.

Any of these features could raise your premiums:

Upgrade Your Wiring and Save

If you are facing high insurance premiums because of outdated wiring, it means that your house is also at a greater risk of fire. It's well worth your while to ask an electrician about what it would cost to replace your wiring system with a whole new setup to protect your home and family. Cheaper insurance is just the icing on the cake.

Many of us can forget about our households energy consumption in the mist of busy daily life.  However, for those who look a bit deeper into specific energy costs, families will be able to determine where their homes’ energy is going and can make adjustments to reduce their energy bills.

According to the U.S. Department of Energy, as much as 45% of your homes’ energy goes towards space heating. This means your heating, cooling, and air conditioning system is going to have a huge impact on your usage. Make sure you have checked your house for any leaks and that the appropriate insulation is installed or you will be losing heat that you have paid for.

Much of your other costs are coming from appliances and lighting. Lighting costs can be controlled by using energy efficient bulbs like LEDs. Make sure you are also turning off the lights in rooms you are not using. When running your appliances, try to use them only when you have full loads. It goes without saying that running the dishwasher or washing machine at half capacity will cost you more. If you can bundle more or wait for a larger load you can keep the number of times you are running your appliances down.

One way to determine your usage is to use an energy monitor. These types of devices cost around $30 to $40. They will let you know how much energy you are using to turn on and run these appliances or electronics. BC Hydro has also supplied a calculator you can use to estimate the cost per year. Sometimes upgrading your appliances can save you hundreds per year in efficiency.
