Sometimes, it can be difficult to understand changes on your electric bill and even harder to determine what you can do to bring monthly costs down. TES Engineering recently attended a seminar that discussed First Energy rate structures and the company’s planned impending rate increases. In this blog post, we hope to break down the […]
Basic electrical calculations involve three parameters, volts, amps and watts. Volts Here in the United States, we design according to specific voltages provided by our utility companies. In residential construction, we often have 120/240V, single phase, 3-wire, while in commercial construction we typically have 120/208V, 3 phase, 4-wire or 277/480V, 3 phase, 4-wire (although older […]
Let’s face it: sometimes, the wall isn’t the most convenient place for an outlet. Never fear, though, electrical engineers to the rescue! We can put your outlet almost anywhere you want, within reason, of course. When our clients want power, data, and/or audio visual connections away from the wall in commercial buildings, office areas, schools, […]
The construction drawings are done, the specifications are complete, and bidding has commenced. A few days before bids are due, however, the contractor suggests replacing copper conductors with aluminum conductors – a suggestion that may be a value-engineering line item, or a qualification item within the bid. But what are the technical aspects of making […]
Selecting an electrical distribution voltage for a multi-tenant commercial building is often based on prior lease agreements, previous projects, incomplete information, or intuition. Our research provides guidelines with economic justifications. Each type of service has its advantages. 208V requires less electrical equipment in the Tenant lease space and is therefore less expensive for the Tenant. […]
