This blog’s creation originated from Peninsula Light Co.’s grounding blog which can be found here. Therefore, it is necessary you have and need to maintain a NEC code-approved ground system as part of your electrical system. The SPD works by shunting damaging electrical surges away from your sensitive electronics to ground, and they need the best possible ground to work properly. The best surge protection equipment is much less effective without a properly installed and maintained grounding system. With insufficient grounding, varying voltages in the home may cause damage to motorized appliances due to under voltage or damage to electronics as a result of overvoltage.Īnother critical issue relative to sensitive electronic equipment is the proper installation and operation of surge protective devices (SPD). MENNEKES is a leading manufacturer of pin and sleeve wiring devices, switched and interlocked receptacles, disconnect switches and power distribution. Proper grounding of your home and business is important to eliminate or minimize the possible damage.

Should a tree branch fall, or a car hit a pole, the service wire from the utility system to your home may be disrupted.

Proper grounding provides stability to your home’s electrical system and reduces the impact of these surges. In addition, voltage spikes can occur when large appliances or heavy machinery at nearby locations are switched on or off.

High voltage surges are often caused by lightning strikes on or near power lines.

Number of auxiliary contacts as change-over contact: 1: With integrated under voltage release. Protection against power surgesĪmong the various situations that may occur on your electrical system, the most common are high voltage surges, and damage or loss of one of the service conductors. Molded Case Ckt-Bkr, 125A G Frame, 25 kA at 480V, T/M - Fixed Thrm / Fixed Mgntc, 3 Poles, 70A, 80 Percent MCCB, No Bus Bar Mounting, NONE, 250V AC/DC, NONE, Aux. If you have concerns about your business or home grounding, contact a licensed electrical contractor. If you do not provide proper grounding in accordance with the NEC, there is no way to mitigate electrical damage that may occur beyond your electrical panel. Unfortunately, we have no control over how well your electrical panel is grounded. If soil conditions change due to drainage or other factors that affect soil moisture, a ground rod that was acceptable at the time of installation may no longer meet approved requirements. Ground rods that are installed in rocky or dry soil should be checked to make sure they still have a low resistance. Ground rods that are bent over, have disconnected wires or are severely corroded must be replaced. This reduces the effectiveness of the ground. Rods that are not fully installed may extend a foot or more above the surface of the soil. In some cases, problems with ground rods are easy to see. Join your host, Todd Reed, as he connects with the owners and pros who design, build, and maintain our electrical, communications, and industrial world. However, sometimes ground rods extend a few inches above the surface, making it easy to inspect the connection. The tops of the ground rods are typically below the surface and may not be easy to inspect. Below the surface, the wire is connected to one or more ground rods. Typically, this is a copper wire about one-fourth-inch in diameter and can be seen going down into the soil.

Causes of damage include corrosion, freeze/thaw cycles, landscaping equipment or careless installation of grounds for other equipment, such as cable TV, security systems or generators.Ī visual check of grounding can be done by inspecting the wire that connects the electrical panel near the meter to the ground rod. Ground rods and their connections to your business or home’s electrical system may be damaged over time and must be properly maintained. Includes 2 AAA batteries.Ground rods are simple and inexpensive but are crucial to protecting your electric equipment and appliances. The 2202-20 is also designed with a green "Power On" indicator light so you know the voltage detector is working properly before use. The durable tip allows for easy checking of power outlets. A visit that allows oral communication and visual contact between the inmate and the visitor, but prohibits any physical contact between them. Non-contact voltage detection technology Extra-bright LED work light makes working in dark areas easy Category IV 1,000-Volt safety. The standardized bridge accessories of the CLIPLINE complete system enable simple potential distribution, bridging between non-adjacent terminal blocks, and.

With a built in bright LED work light the 2202-20 is two tools in one. The 2202-20 can detect between -Volt AC and has an industry leading safety rating of CAT IV 1000-Volt. The Milwaukee 2202-20 Voltage Detector with LED is used for residential, commercial and industrial applications.
