Disconnects 101

A safety switch (or disconnect) monitors the electric current in various applications. They are used with major industrial machines such as conveyor belts, line equipment, heavy appliances, and whole-system electrical protection. You may need to disconnect your equipment from the electrical supply for repairs, maintenance, or emergencies. Safety switches monitor the current and detect faults in the electrical infrastructure so that in the event of an electrical leak, a short-circuit, an overload, or equipment failure, the safety switch will nearly instantaneously (within milliseconds) shut off power to the system.

Safety switches are an NEC requirement (National Electrical Code) in all industrial settings and were established by the National Fire Protection Association. The NEC requires that a safety switch be “in sight” or visible and no more than 50 feet from the equipment it controls.

There are many types of safety switches, and the model you need depends on the conditions inside your working environment. Not sure what type you require? Call J&P Electrical, our experienced and motivated team of staff can help, and if we don’t have the product you are looking for, we’ll find it!

Surge Protection 101

For many people, technology is the center of their attention span. Between televisions, computers, smartphones, ovens, dryers, tablets, security systems, dishwashers, etc., many aspects of our lives are assisted by an electronic device. As people expand the number of devices they own, power protection should increase as well. When they suddenly stop working, it can sometimes seem catastrophic.

Power surges are abrupt yet short-lived spikes in voltage that result in strong disruptive effects on the entire electrical system. Thousands of dollars worth of damaged electronics can result from these swift power surges. Typically caused by lightning strikes, power surges can also occur in small instances that damage equipment over time.

Read on for some tips to protect your devices from power surges.

Protect electronics: Ensure power lines, phone lines, and television lines are protected, as well as outdoor items such as pool equipment, air conditioners, and landscape lighting.

Indoor surge protection: Beyond the outside surge protection, it’s imperative to safeguard the plugs as well. Surge protector strips can be used to protect electronics inside the building.

To protect your devices, lightning surge protectors installed by electricians can redirect surplus voltage and current into a grounding wire. While the 120 voltage runs through circuits, electronics are protected and won’t lose power through a surge.

Professional surge protection includes the following:

  • Facility Guards: highest level of protection – can handle surges up to 400,000 amps
  • Transient Limiters: commercial/industrial – can handle surges up to 100,000 amps
  • DC Surge Protectors: transient or significant surges – can handle surges up to 10,000 amps
  • Data Line Protectors: control/telephone lines
  • Hybrid Surge Protectors: specialized protection for process control or computers

For surge protection equipment, contact the electrical contractor supply specialists at J&P today.

What to Do with Water-Damaged Electrical Equipment

April showers lead to May…electrical equipment damage? Springtime can bring damaging thunderstorms and flooding. In the typical rainy season throughout the United States, flooding is a byproduct. Determined by the Federal Emergency Management Agency, flood zones are mapped out based on drainage characteristics, grading, and buildings in the area. Flood exposure depends on whether the building is within the 100-year flood plain. Flood maps are only reliable until the following construction season forces grading to change, which affects drainage. If a building is within an official flood plain, mortgage holders typically require the owner to possess flood insurance.

If electrical equipment has been submerged, it should immediately be de-energized from a safe location, preventing further damage to equipment. Flood water generally affects equipment in a building as it contains sediment such as plant residue, sticks, mud, dirt, hazardous materials, oil, and more. When floods strike, some sort of advanced warning is usually given, which might allocate some time to de-energize equipment and mitigate electrical hazards, including arcing and shock.

The first question is whether the equipment is damaged and how much exposure it has had to water. If an entire room is flooded, a significant exposure issue will arise. If some fine water spray misted the electrical equipment, the damage probably would not be too substantial. Immediately wipe or clean the equipment to minimize corrosion. Equipment manufacturers can offer guidance and recommendations based on their products.

After water damage, a great resource to look to for suggestions is NEMA GD-1, “Evaluating Water-Damaged Electrical Equipment.” This document “Provides advice on the safe handling of electrical equipment that has been exposed to water. Outlines items that will require complete replacement or that can be reconditioned by a trained professional. Equipment covered includes electrical distribution equipment, motor circuits, power equipment, transformers, wire, cable and flexible cords, wiring devices, GFCIs and surge protectors, lighting fixtures and ballasts, motors and electronic products.”
