Fundamental electrical engineering concepts and theory
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
I'm a fan of using manufacturers catalogues. There are two main reasons for this. Firstly, if your involved in the purchase of equipment, you will likely...
IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...
The term 'N+1' relates to redundancy and simply means that if you required 'N' items of equipment for something to work, you would have one additional...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
