Vikas has the right idea if you are worried, and need to do a quick check.
20 years ago, we were commissioning a power station, and the 22kV connections had to be made to the transformers. These joints are silvered copper, and have around 20,000 amps running through them, so clean and properly tight is important.
One of our young electrical engineers chased one of the savier tech assistants for a torque wrench..."and get a calibration certificate for it"
Tech Assistant quick as a flash responded "not much point, torque wrenches are all calibrated at sea level in a lab, and we are at 900m above sea level."
Which had the young engineer ringing across the country for a torque wrench altitude correction curve.
