Hi,
I've had a few occasions where a 3 pin plug or the switch socket outlet get burnt. This usually happen to chiller unit.
The cable was properly size up according to the drawn current and also well above 13 Ampere when those single phase 3 pin plug are used.
The trouble usually happens when the chiller compressor runs out of refrigerant. In normal situation, the compressor will on and off according to the set water temperature. In the event where compressor run non stop because the water temperature does not reach the set temperature, the heat starts to build up. Usually the pin of the plug will get hot and followed by the switch socket out and then the plug.
My question is, how much continuous current and how long a time it will take before all the heating up takes place, assuming ampere is below 13 Amps and it doesn't blow the fuse.
Are there any standard tables that we can refer to.
Thank you all.
