Massachusetts electrical licenses expire on July 31, 2019. The Massachusetts Board of State Examiners of Electricians requires licensees to complete 21 hours of electrical continuing education every 3 years in order to renew their license. If you did not successfully renew your license in 2016, and your license expired July 31, 2016, make sure to complete your continuing education and renew your license now! If your license expired July 31, 2016 and you do not renew by July 31, 2019, you will lose your license and will need to re-test to become licensed again.

Back in the rural south, around 1940, power companies would mail flyers to their customers at the beginning of summer. These flyers would give tips on how to stay cool during the hottest days ahead. Some of the tips were; grow ample shade around your residence, stay inside during the hottest part of the day, use open windows for increased air circulation, and keep wet towels available to cool your forehead and neck. Homes, in those days, were designed to facilitate air movement. Large porches and arched ceilings in hallways enhanced air currents that moved freely through the structure. These conditions were the norm for homeowners before the availability of affordable air conditioning.

Ground fault protection is not new, having been introduced in the 1971 edition of the National Electrical Code. GFCI devices have saved many lives since then by preventing shock and electrocution. As you may know, they contain a small transformer that detects current leakage from the phase to the grounded (neutral) conductor. That is why they work even in circuits that do not have a separate grounding conductor. These devices are designed to interrupt current when the leakage reaches a threshold of 4 to 6 mA, just shy of the amount of current that can cause injury to the human body.

The 2017 NEC now requires meeting rooms measuring 1,000 square feet or less to be equipped with 125-volt 15 or 20 ampere receptacles. This new requirement will help serve today’s trend that requires we travel with a myriad of electronic devices to meet our daily personal and business needs. This new Code-reference, 210.71 Meeting Rooms, is found in Article 210 Branch Circuits, Part III. Required Outlets, and is only applicable to meeting rooms or areas measuring 1,000 square feet or less. The qualifying room or area is to be determined by measuring wall-to-wall space, as well as space created using movable partitions.

The Isolated Ground (IG) is a type of equipment ground that, in theory, reduces interference experienced by electronics and instrumentation from radio frequency (RF) noise, by connecting that equipment directly to the grounding terminal of the service equipment, without ever making contact with another metal component or grounded surface, that could potentially be serving as an antenna for airborne RF noise.

The NEC has long regulated the required space around electrical equipment installations so that a worker who is going to examine, adjust, service, or maintain equipment that may be energized is not exposed to excessive danger from live (ungrounded) parts. The worker must have enough space available so as not to contact a surface that could effectively make his body a path to ground. In the past, equipment installations above a drop ceiling, such as small transformers, air handlers, VAV’s, and the like, have not been addressed, and the enforcement of Article 110.26 in these spaces has been difficult at best, as the space above a drop ceiling is often very crowded.
