What are the Right Standards for Fireproof Enclosures?

There are several types of different variations of the fireproof enclosure design. It all depends on what the application requirements are and what are the dimensional and operational parameters of the device that is being used. In addition to this, there are standards in the basic design principles that are being practiced by the community when it comes to the fireproof industrial enclosure systems. These include:

  • Cables and connectors that does not have a direct entry into the enclosure.
  • The external flange displays the strong metal-to-metal bonding or have a vented joint that should not exceed the allowance for the maximum gap.
  • The rubber and other materials has the possibility of deterioration should not be utilized in sealing the joints.
  • All the externals needed in facing the joints and the flanges are installed and machined within the limits of preset minimum distance that exists between the inner and outer sides of the enclosures.
  • Any fasteners should be utilized to properly secure all the covers that are being hooded.
  • The shaft and the spindle bearings should be able to maintain a specific minimum length and maximum radical clearance in accordance to the application requirements.

The specific standards for these fireproof electrical enclosures should greatly vary depending on the type of the fireproofing project that is going at hand, but the meticulous and careful testing should be always implemented to carefully determine the electrical enclosures’ effectiveness. Once the required tests for these involves the identification the maximum pressure that could result to gas explosion internal of the electrical enclosure, and then exposing the electrical box to a higher temperature in tis environment is necessary to measure and evaluate its protection levels.

This type of test is also being utilized to effectively verify whether the explosion inside the enclosure will ignite in the presence of combustible atmosphere and spread fire to the external systems.

The integrity of the structure is one of the most crucial and critical characteristics the fireproof enclosures has and makes it important for the electrical enclosure to be tamper-proof and highly efficient. By installing and repairing the electrical box requires specific training and certification and the process should be able to follow all the standard in safety protocols and manufacturer recommendations for all of its components.

The cables and the conduits utilized for the connection of the fireproof electrical box should also be able to play a very important role in the reduction of the ignition risk. Even if the fireproof standards might vary in different manufacturing companies.

How to add A Unusual or Non-Conventional Parts or Accessories to Your Electronics Enclosure?

We discovered that our TV stand would not work in the living room. Yesterday, we had spent the day scrubbing his apartment so the car was full of cleaning supplies such as vacuum, mop, and garbage cans. Since we passed a furniture store we decided to stop and just check out what was available.

Finding the perfect stand at a great price, we knew we had to make the purchase immediately. However, there would not be room in the vehicle. Our sales assistant helped us come up with a non-conventional method to pack all of the items in the car and we made it home in record time.

Another area non-conventional items or methods are common is in electronics. There are many standard components such as printed circuit boards, wires and connectors, and plastic enclosures to hold it all together. Once a customer asked how to attach a swivel to his enclosure.

He was inventing a product that could be worn on a cord around a person’s neck. In order for the product to work correctly, it had to be able to rotate on a specific axis, which is where the swivel came in.

This is not a very common issues that is usually being encountered. Even though, there are wide variety of electronics enclosure product line. This line is versatile enough to be able to accommodate even the most non-conventional items under electronics equipment.

The companies would only need to machine or put a round hole on the enclosure. At the location where the two pieces should come together. Especially when the product is being finally screwed together. This will now allow some of the parts to slide better unto the grooves on the swivel. And it can also secure the swivel properly while maintaining the maneuverability around the axis.

The 21st Century’s Lighting Revolution: What is it all about?

The Department of Energy actually did was in last 2017, they stated that the number of light bulb classifications the Congress has explicitly stated is not included in the formal definition of the general service lamp. However, these classifications are now included. The lamps that are being included in classifications of specialty light bulbs are differentiated according to their special applications, sizes, and bulb shapes.

To be more specific, DOE separated the incandescent reflector lamps, directional light bulb (this is commonly known as spot or floodlights used to focus lighting to a specific area) small decorative light bulbs that comes with different shapes of a candle flame, small globe round shape lamps, and light bulbs that are tubular shaped which are commonly used in orchestra or furniture displays.

With this in mind, the Department of Energy included the light bulbs that cannot be screwed or installed on the common general service lamp socket because they tend to have a smaller candelabra lamp base. They also have the intermediate size bases for lamp bases that can come in a plug-shaped pin that can be also installed on a wall, ceiling or floor receptacles. Congress never stated that these type of light bulbs are classified as general service lamps.

With these facts together, it is not right to depend on the alleged rollback for energy saving to be heavily dependent on the removal of incandescent versions of the mentioned specialty lamps just because of the illegal and misconstrued definition of a general service lamp. This claim is not cognizable.

The Energy Savings Claim is Being Exaggerated.

During the course of rulemaking about the general service, lamps happened from 2014-2017, Department of Energy the congressional appropriations rider that has limited ability to allocate appropriated funds to effectively implement energy conservation rulings for these special type of incandescent lamps. This is done so that it could not be researched, collected, or even look at the data gathered about these lamps.

In effect, the Department of Energy was going data blind that concerns about the general service incandescent lamps or other types of these lamps. Even if a citizen submitted information about these incandescent lamps to the department, DOE will not bother to even look at it. NEMA organization did this and DOE refused to even consider it.

The importance of DOE’s restrictive interpretation is it shows that the Department of Energy was not primarily concerned in effectively tracking an economic event that is currently taking place. The NEMA and other NGO bodies (from the energy efficiency community) are heavily dependent on this interpretation. There is now a rapid adoption of LED lighting technology that leads the way to even more drastic decline in worldwide installations and shipments of incandescent lights happening since 20003.

With this in mind, the general service lamp decline was now being tracked by the Department of Energy. However, the body failed to capture the effects of the recent decline, more so from recent years. The body’s estimates already ended in 2015, and they failed to capture a drastic fall in years 2016, 2017, and 2018.
