Q:I have surge/lighting protection on my home. Am I totally safe from lighting strike?

​A: No. Surge/Lightning Protection only offers additional levels of protection. Nothing can guarantee completely against Mother Nature and where she chooses to strike.

Q: If I have surge/lightning protection on my main service, should I use point-of-use surge protection at my TV, stereo, computer, etc.?

A: Yes. Main line surge is no absolute guarantee and any additional surge protection down-stream in the system offers a greater level of protection; though, nothing is absolute when it comes to the power of Mother Nature.


Q: I have a 110 volt outlet on the exterior of my home. Can I plug my Christmas lights into it?

​ A: Yes. Within reason, if the quantity of lights creates a load greater than the capacity of the circuit breaker, the breaker will trip off. In this event, additional circuits may be required to accommodate your holiday display.


Q: Can I plug any 110 volt device I wish into my regular 110 volt outlets throughout my house?

 Yes. Though, if the device exceeds the capacity of the circuit, the breaker will trip off.


​Q: Can I plug my coffee pot and toaster oven into the same kitchen counter outlet?

​ Yes. Though, if the two loads exceed 20 amps, your breaker will sense overload, do its job, and trip off. Under this condition, you must plug one of the appliances into a different kitchen outlet on a different circuit, in order to minimize overloading a circuit.


Q: When my air conditioner cycles on, I notice my lights blink. Is this normal?

​ Yes. This is a common occurrence when large motor/compressor loads start. These devices cause a minor momentary voltage drop, demonstrating itself as the blinking in your lights. This has no immediate negative effect on the electrical equipment within your house. Over time, surges and/or voltage dips can minimize the life of your valuable sensitive electronics. A whole house surge protection system will give added protection for such occurrences.

​Q: How do I reset my breaker when it has tripped off?

​ First, disconnect any additional devices that may have caused the breaker to overload and trip. Breakers are mechanical devices and must be turned all the way off before turning before turning back on. Remember this is a mechanical device, so this may require several attempts. If this fails to reset the breaker, there may be a more serious problem. Call ESU.


Q: Why do I blow fuses or why does my circuit breaker trip?

​ Except in the case of ground fault interrupters, which are susceptible to moisture and/or weather conditions, fuses and circuit breakers should not trip. You can unplug an appliance to determine if it causes the problem.


Q: What is the difference between a breaker panel and my old fuse panel?

 Both devices, either breaker or fuse, are designed to trip (turn off) in the event of an electrical overload, i.e. 20 amps of electrical load on a 15 amp circuit would cause a trip. The only difference is that a breaker is mechanical and may be reset. Whereas, a fuse is one time only and must be replaced. Please note: Modern breakers are much more efficient and offer greater levels of protection.




Q: What is a GFCI device or breaker?

 GFCI stands for Ground Fault Circuit Interrupter. In layman's terms this device protects you from electrical shock. When it senses the slightest increase in resistance resulting from ground fault, (i.e. the use of electrical devices in or near water), it turns off to protect you.
