A hot connection where the stab of a fuse is held by the fuse holder is common in motor starters and fused switches. |
One
hazard is that the fuse will open due to heat from the connection.
This may stop the motor and possibly the entire process.
Another danger is the possibility of fire. |
A hot fuse connection such as this is usually simple to repair. |

| Transformer radiators cool the oil by natural convection. | Here you can see that the center fin is hot while the other fins are not. This is because the oil level is low and cannot reach all of the fins. | After adding oil to the proper level, it reaches all of the fins. This enables efficient cooling. |

On
this 4160 volt transformer, the center phase high voltage bushings and the
line connection is running hot. After investigation and repair all bushings and connections are normal. |
|
The right phase bottom cable connection on this motor starter contactor is hot. The same starter after repair. The heat inside the contactor is from the electromagnet and is normal. |

The tip of the blade on the center phase, and to a lesser extent the left phase, is hot on this 13.8 kV pole mounted disconnect switch. After the repair (replacement in this case) all is fine. |
