affordable and reliable‚ have flexibility of control‚ and offer significant electrical energy savings through greatly reduced electric bills. They are used in a wide variety of applications for various reasons. For example‚ they are the most effective energy savers in pump and fan applications; they enhance process operations‚ particularly where flow control is involved. VFDs provide soft-start capabilities‚ which decrease electrical stresses and line voltage sags associated with full voltage motor start-ups

FLOOR PLANS What is a floor plan? - It is a flat representation of only two measurements – the length and width (or depth) of an area or object as seen overhead. It is as though one were viewing the area from far up in the air‚ and all that could be seen is a flat‚ graphic representation of height‚ with everything flattened out. The display person‚ like an architect or engineer‚ is a professional and should not be given to whims or fancies that will not come to terms with reality

ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in
