NEMA and IP ratings both measure the same thing: an enclosure’s ability to withstand the ingress of dust or water. This matters because watertightness is not a binary concept: housings are not simply waterproof/not waterproof. Varying degrees of pressure play a huge part in how well your enclosures will cope with exposure to water or dust. A splashproof enclosure will not resist prolonged immersion.
Littelfuse, Inc.,, an industrial technology manufacturing company empowering a sustainable, connected and safer world, reported its annual electrical safety survey exposed that almost all respondents had witnessed someone working on or near energized equipment of more than 50 volts. Over 50 volts puts people at risk for electrical shock and electrocution.
As more electrical devices are deployed in industrial applications, the need to protect these critical systems increases. Unexpected power outages lead not only to higher maintenance costs of electrical equipment but also to lower operational efficiency, productivity, and overall business revenue. To ensure a stable power supply, facility managers need to monitor power quality so that electrical devices are protected from unwanted interruptions and damaging fluctuations.
An Industrial control panel is an assembly of two or more components — such as motor controllers, switches, circuit breakers and control devices. They are used in various end-use applications including the operation of industrial electric motors and drives, production, assembly and conveyance. Control panel builders are responsible for the construction of electric control panels for manufacturing machinery and other various types of equipment.
The energy transition has brought both challenges and also new opportunities. For example, if a wood-fired system also provides process heat, then lucrative subsidy programs can be utilized. The energy data management system which is, among other things, necessary for to apply for subsidies, can be easily realized, as Endress Holzfeuerungsanlagen GmbH has proven.
Even in 2021, in a time when Industry 4.0 and IIoT have accelerated the evolution of industrial panel and switchgear engineering, there’s still much in the way of misinformation and misconception about how manufacturers should go about defining a modular enclosure and what truly categorizes an industrial enclosure as modular. Whether it’s a matter of naming convention or just a misunderstanding of the traits and attributes that comprise a modular enclosure system…
Allied’s “Ask The Expert” series taps into the experience and expertise of key thought leaders and subject matter experts from the more than 550 global suppliers Allied work closely with to bring customers solutions for their most challenging problems (and the daily ones, too). In this edition, they talk with Tom Ballou, sales and marketing manager for Hammond Manufacturing, about the factors involved in choosing an electrical enclosure to suit the environment it will be in and how playing it too safe can lead to unnecessary expenses.
The United Nations estimates that world population will climb from 7 billion to 9 billion by 2050. This means higher demand for food for the growing population, and more work for the farmers to produce more food.
New York state legislature is hoping to add additional protections to the state’s critical infrastructure via a newly proposed cybersecurity bill. The bill leverages the industry-adopted ISA/IEC 62443 series of standards to shape metrics and benchmarks for operational technology cybersecurity. If passed, the bill’s measures would be applied to the state’s critical infrastructure facilities.
In the development of any electrical project, it is fundamental to count with a comprehensive and accurate manufacturers’ catalog. In fact, the reliability and the immediate availability of exhaustive contents is key to any technical design professional keen on guaranteeing the quality and integrity of the electrical projects. In order to guarantee safety, any electrical installation must comply with the local electrical requirements and standards.
This year Weschler Instruments celebrates its 80th year as a supplier of meters and instrumentation. Much has changed in electronic measurement equipment and technology since 1941. Vacuum tubes were replaced by transistors and then integrated circuits. Analog indicators became digital readouts and then graphical touchscreens. Manual operation migrated to automatic sequencing and then fully computerized tests.
A main panel is an installed box where the power from the utility company enters the premises. A subpanel is an installed features that acts as a middle ground for the main panel and other types of circuits that are connected to your property. In this brief guide, Hardcore Electric will provide you with information pertaining to main panels and subpanels and instruct on their usage.
Situation: Worker approaches the enclosure and the disconnect switch for the 480V power source is in the OFF position. The disconnect switch has failed with one phase (L1) in the closed position (L2, L3 are open). The ground leads of the devices are NOT connected to ground because of an improper installation or termination failure.
Control panel builders utilize several factors to create optimal functionality. Taking these considerations a step further to ensure safe operation, designers should adhere to widely accepted standards, notably Underwriters Laboratories (UL) UL508A. UL508A provides guidance for panel design, including the approved method to determine short circuit current rating (SCCR).
More often than not, there’s an ideal tool for the job. For example, you wouldn’t try cooking a steak in the microwave, as that particular tool is not engineered for properly preparing that kind of food. You’d of course cook a steak on the grill, as that type of heating application is best designed to heat the steak to your exacting specifications. In today’s industrial enclosure marketplace, there are numerous options for enclosure material, and each has its own specifications, ideal applications, liabilities, and value propositions.
Whether the utility provides electricity, gas, water, or sewage treatment, management has a duty to protect employees by providing a safe work environment and Personal Protective Equipment (PPE) required for the job in the facility and in the field. However, despite various PPE options, many utilities fail to supply or specify important lighting tools – namely headlamps.
