The let through energy
Like we well know electrical components have a lifetime, which is calculated considering the energy that trasverse them. The electrical energy like expressed from the english physician James Prescott Joule its explained like it follows:
Electrical Safety and Arc Flash Mitigation
Differences beetween FLA and FLC
THE DOUBT:
In North America, each motor has two current values:
- Full-Load Ampere (FLA)
- Full-Load Current (FLC)
What are the differences and when are the...
UL and CSA Conformity
Equipment Grouping
In an explosive atmosphere, only suitable equipment must be installed: suitable means that they cannot ignite the explosive atmosphere. There are 3 types of Explosive atmospheres
ATEX Risk
Equipment Protection Level
In an explosive atmosphere, only suitable equipment must be installed: suitable means that they cannot ignite the explosive atmosphere.
Process Safety
The breaking capacity of protection
One of the problems related to the dangerousness of electrical current is the fact that cables and utilisers can catch on fire if traversed by a current bigger than the one predicted for its normal use.

Spare capacity in Industrial Control Panels
The Doubt: In an Industrial Control Panel, is it required to leave a certain Spare capacity for “future” development?
Electrical Safety and Arc Flash Mitigation
IEC 61508 (all parts)
This is the “mother” of all Functional safety standards used in several industries worldwide. It was written in order to allow the use of Electronic components in safety critical systems.
