I have a max VD of 5% per NEC -- I understand that the NEC does not specify VD for service conductors, but since it specifies it for all others, I'm just going with that.Now, the fun part. My question is not really about the calcs, but rather what values for R to use. The ...
Inrush current makes the conductors for motor circuits a particular case. Part II of NEC (National Electrical Code) Article 430 comprises rules to compute the ampacity of the branch-circuit conductors for various types and combinations of electric motors and non-motor loads. Section 430.6(A)(1)...
Calculating conductor size is very important to the electrical and mechanical properties of a bus bar. Electrical current-carrying requirements determine the minimum cross-sectional area of the conductors. Mechanical considerations include rigidity, mounting holes, connections and other subsystem elements. Th...
Cable installations for three-phase systems consisting of parallel single-core cables circuits carry different currents due to inductive coupling. The authors discuss how supplementary installed additional conductors grounded on both ends show several beneficial effects: Balanced outer conductor currents, impro...
Electrical Service amperage: what is the limiting factor? The safe and proper service amperage available at a property is set by the smallest of: the service conductors, the main disconnect fuse or switch, or the rated capacity of the electric panel itself. The inspector should consider all thr...
