    Cable Doubt
AI Thread Summary
The discussion focuses on the suitability of a 150A MCCB breaker paired with a 95 sqmm cable for a load current of 135A. Participants emphasize the need to consider conductor material (copper or aluminum), insulation type (PVC or XLPE), and cable configuration (single-core or multi-core). Environmental factors such as installation conditions (air, conduit, underground) and surrounding temperatures are critical for determining cable performance. Additionally, the impact of thermal resistivity and proximity to other cables is highlighted as important for safety and efficiency. Proper assessment of these factors is essential to ensure compliance and prevent overheating or failure.

hello
i have got a 150A breakerMCCB and the cable connected is 95sqmm and load current is 135A
is this correct or any changes is to be made?
what will happen if the supply is given from 420v 3phase system

You have to state:
1) the conductor: copper, aluminum?
2) insulation: PVC, XLPE?
3) single-core or multi-core cable?
4) in air at 40oC, in conduit, in underground [in duct?]
5) if it is embedded in Earth what is Earth temperature and what is the thermal resistivity.
6) how many other cables are in close vicinity?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
