Abstract
A load calculation device for determining the maximum electrical load that can be applied to an electrical circuit includes determines the temperature differential (ΔT) between a section of the electrical circuit and the ambient air temperature in which the section of the electrical circuit resides. The actual electrical load applied to the electrical circuit is also determined as is the design load of the electrical circuit. The maximum electrical load that can be applied to the electrical circuit is then determined based on the temperature differential and the electrical load applied to the electrical circuit and the circuit designed load. The load calculation device may be applied to an electrical joint and may be used to calculate the maximum temperature differential allowed for a given current to be applied at the electrical joint. This is particularly beneficial in connection with detecting and preventing electrical joint failure.
