Floods and Your Home Electric System

We are quickly coming up on the wettest months of the year all along the East Coast. Winter and spring flooding are not uncommon and while it is not possible to stop Mother Nature, we can be proactive in our response. What follows are a list of measures to take before the water hits to ensure the greatest amount of safety and experience the least amount of damage.


• Make sure your gutters, downspouts and drains are clear. Keeping these areas unobstructed will allow the water to move away from the home’s structure as quickly as possible.
• Move as much of your goods and furnishings as possible from the lower floors to the upper parts of your home, such as to a second story or attic. Store materials in waterproof containers. This should include valuables, clothing, and small electronics.
• Create a record of your home goods, including the receipts and pictures of those items that may be very costly to replace. Make sure this information is tucked away in a dry, safe place and easily accessible.
• Turn off all utilities in advance of a flood. Your water, gas and electricity are all subject to creating potential hazards for homeowners and rescue personnel who may venture into the area. While it may be inconvenient to go without these utilities in the short-run, turning them off may save lives in the end. In response, be sure to have plenty of bottled water, flashlights and other non-battery-operated sources of light available. Today there are many options for staying out of the dark.
• Elevate your appliances on cement blocks to keep them off the floors. Contact your utilities expert if you need assistance. Do not unhook your appliances without the oversight of an expert. Wrap your air conditioner completely in plastic as well and be sure it is in the off position.
• Open the windows of the house on the lower levels. If there is flooding they will not be able to keep the water out and will only be subject to breaking. In this way you may not have to replace the windows after a flood event.


Again, no one is claiming a flood is on the horizon but it’s always better to be prepared. If you are looking for professional electrical support in case of a natural disaster, contact the experts at J.M. Mullen Electrical Services. It is our pleasure to serve you.

Your Annual Electric Checkup

January is traditionally a time for making resolutions and refreshing your life. During this time of year, people are more inclined to visit the dentist, doctor, and optometrist for annual assessments of their health. It is also time to review the state of your home from top to bottom as well. Included in this to-do list is an annual electric checkup.

Here are the benefits

• An annual check up of the electrical wiring and boxes in and around your home will help to reveal any potential hazards that could result in a fire. Outdated wiring, fixtures and electrical systems are a significant cause of home fires, particularly in the winter when these systems are taxed more than most times of the year. Annual electric preventive checkups will ensure your home system is in healthy working condition.
• Annual checkups of your electric system will also uncover improper overloading of the system. For example, perhaps you have an extension cord with too many appliances drawing electricity from this single source. All too often this can spark a fire. Annual checkups help to ensure the safety of all occupants.
• These checkups will also include an assessment of your appliances and other electric-powered equipment that have the potential to cause a fire because they may be outdated or can no longer be operated safely. These are items that will need to be replaced – a seemingly costly choice that pales in comparison to losing an entire home or injuring or causing the death of occupants.
• Ensuring that your home is up to the latest local, state and national electric standards that are imposed on structures. These standards change over time and it is incumbent upon the homeowner to keep up with this information and be compliant.

An electric inspection will include:

• An examination of all outlets.
• An examination of the circuit breaker or panel.
• An assessment of scenarios within the home that are subject to potential overloads.

Now, do not expect these annual inspections to come without a cost. You have to pay for your other annual checkups – right? But, when you weigh the benefits against the cost, I expect you’ll be scheduling your appointment today.

The Most Common Renewable Energy Resources

While the most talked about renewable resource for generating power is usually solar, there are other resources just as popular and effective. That is not to say that harnessing the sun’s rays to generate electricity is not highly effective, it is one of the best alternatives for reducing carbon emissions that are instigating climate change.

As well, hydropower is an energy source that has been in use since 1880. People are usually unaware of the fact that hydroelectric dams have been the single largest source of renewable electricity generation for the past century.

But it is wind power that is stepping up to become the most common source of energy in 2019. A whopping $145 billion in investments over the last decade alone all but ensures this form of energy generation is expected to be permanent and a leader.

It should be noted that even with all this money spent on wind power it is currently only providing 6.5 % of electricity to Americans in 2018. This figure is expected to rise only marginally in 2019 to 6.6%. These figures are mirrored for hydroelectricity which, as an aside, tells us that our efforts to capture natural and renewable resources for the purpose of generating electricity fall short of our needs significantly.

Altogether, statistics show that 17% of electricity in the United States comes from renewable resources. That means solar only accounts for approximately 4-5% when combined with other renewables. Another 20% is generated from nuclear energy, leaving the remaining amount coming from fossil fuels (and negligible things like wood, biomass, etc.).

The purpose of sharing this information is not to persuade or argue for one energy source over another. However, it would be instructive to become educated on the various sources of energy that will be powering your home, this country and the world in the future and, perhaps, make energy choices that you believe will be most valuable in the long run.

Meanwhile, if you have questions about the state of electricity in your own home or business, we invite you to contact the experts at J.M. Mullen Electrical Services. We are here to serve the needs of our community.

Surge Protectors, J.M. Mullen Electrical Services Annapolis Electrician

Whole House Surge Protection

It’s almost a certainty that somewhere in your house there’s a surge protector plugged into one of your outlets. Most people plug in their televisions, computers, chargers, etc. Every year our dependence on electronic devices grows and so does our need to protect those items. Most people think to protect their televisions, phones, and computers, but neglect the biggest units that need protection. Your stove, refrigerator, washer, and dryer are just as vulnerable to power surges as your personal electronic devices. Enter a whole house surge protector.

Unlike a power cord that plugs into the wall, a whole house surge protector is connected directly to your home’s breaker panel. Because the surge protector is properly insulated, it can be installed on the inside or outside of your home. The power strip surge protector doesn’t have the capacity to protect your electronic devices from large power surges. A whole house surge protector will catch the small and large surges for every outlet in your home.

Look for a surge protector that has multiple stage protection. It must be sensitive enough to take care of small surges and hefty enough to handle the major surges. It’s always best to have this type of surge protector installed by a professional electrician. If you install the device yourself, you’ll probably void the manufacturer’s guarantee and it may affect your insurance coverage. Protect your finances as well as your home and call on a professional.

The unit will have indicators to let you know that it’s working properly. LED lights on the panel will show you the status of your home’s electrical system. If both lights are on, the protector is working and there have been no surges. If one light is on, the unit is still working but there have been surges. If both lights are off, the unit isn’t working and needs to be replaced.

The proper sized surge protector installed correctly could last for the life of your home. And, it may increase the value of your home upon resale. Every safety system you add to your home is an attractive selling point. JM Mullen Electrical Services can recommend and install a whole house surge protector for your home. We’re fully licensed and insured and will provide you with the excellent service that’s built our business. Contact us today for an appointment. ty5
