Circuit Protection Selection Guidance

Tristan Epp Schmidt
Circuit protection devices have existed since 1864; one would think that selection of circuit protection would be a straight forward task. However, it is not. NASA developed a seven-step process for circuit protection selection and both EN3179 and AS50881 provide some guidance. In a past article, Lectromec began to consider the differences between two major […] Read more

Understanding aircraft wire differentiation to improve EWIS

Lectromec Team
The amount of aircraft wire on a civil aircraft has increased in recent decades such that today’s typical aircraft has hundreds of miles of wire connecting all of its subsystems. The increase in the amount of wire on an aircraft, coupled with weight concerns, has lead to progressively thinner and lighter insulation materials. Wires used on […] Read more
