  • Voltage Drop, Ampacity and Wire Size Selection (.pdf)
    The following example will describe how to select the correct wire size for your application. Voltage Drop, Ampacity and Wire Size Selection Voltage Drop, Ampacity and Wire Size Selection. The following example will describe how to select the correct wire size for. your application. 1. First
  • Sizing Circuit Breakers for Self-Regulating Heat Tracers (.pdf)
    is intended to show the technical basis on how circuit breaker sizing is accomplished. Key factors in proper sizing are: (1) the specified start-up temperature, (2) the circuit breaker type. and ampacity rating, (3) the specific S/R tracer start-up characteristic, and (4) the total length of heat tracer
  • Adapting Press-Fit Technology - White Paper
    environmental conditions, such as automotive, has created additional challenges that most existing press-fit parts were not designed to withstand. In addition to the added rigors of vibration, thermal shock, etc., press-fits for such applications have much higher ampacity requirements than
  • CT Safety: How to Avoid the Serious Dangers of Improperly Installing CTs
    Customers often ask why we don't recommend installing our CTs on uninsulated conductors when the insulation rating of the CT is 600 volts. This question most often arises when dealing with large switchboards or motor control centers. The high-ampacity bus bars are spaced out evenly
  • Selecting Harmonics Transformers vs. K-Factor
    . The electrical industry's first response to these four problems was to double the ampacity (current carrying capacity) of the neutral conductors so that they would not burn-up. This is becoming a standard design practice in office buildings. The second response was to beef-up the distribution
