Answer for USA, Canada and countries running a 60 Hz supply service.
Assuming the splices were made correctly, meaning tight, and assuming the wire nuts did not otherwise fail, there is more heat than the wire nuts were designed to withstand. Such splices in a transformer should be limited and eliminated if at all possible. Such splices in a transformer should not be made in close proximity to the coils. If there is not space or a compartment to isolate the splices from the heat, you need to install a different method of splicing that can withstand the heat.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is fusing current?
The fusing current is a value of current that causes the fuse to melt and interrupt the flow of current. Usually, reference is made to the minimum fusing current which is the smallest value of current that will cause the fuse to melt.
What are the causes of fire in electrical circuits?
Overloading the circuit or a device like a power strip will cause the wiring to heat up at it's weakest point and can result in fire, it can also cause insulation to melt resulting in an electrical short.
How do you fix insulation melt back on wire?
You cant it is physically impossible without a machine
A device that contains a thin strip of metal that will melt if there is too much current through it is called?
a fuse
Do solders melt at the operating temperature of a heater?
Good question. There are a few simple answers. Most solders begin to become "plastic" at around 350 degrees Fahrenheit and melt at slightly higher temperatures than even that. If you are asking about a hot water heater: If you are operating your water heating system at that temperature the water will have already boiled off and most likely the heater will either have exploded, the P/T relief valve dumped or both. If you are asking about an electric heater, do not try to melt solder on it. The heating element is electrically "hot" and could present an extreme shock hazard. The best way to melt solder is with with a soldering iron or some kind of torch. Hope this helps
How is friction is connected to waxing the surfboards?
When you rub a bar of wax on a board, the heat caused by the rubbing causes the wax to melt into bumps all over the board.
What causes matter to melt?
Heat energy causes matter to melt. The energy breaks bonds in the matter making looser constructions of the material.
What causes solids to melt?
fire/heat makes matter expand the melt away
What causes polar ice to melt?
Melting of the ice caps Global warming causes the ice caps to melt. As they melt, the moving water corrodes at the remaining ice, speeding up the process.
What causes ice cream melt?
Heat causes any frozen liquid to melt. When a liquid is frozen, all of the atoms come together. When that frozen liquid is heated up, all of the atoms move away from each other which causes it to melt.
What in chocolate ingridient causes it to melt?
Fat.
What causes snow to melt to liquid water?
heat
What form of energy causes chocolate to melt?
Heat
Which type of energy causes snow to melt?
Thermal.
What causes a glacier to begin to melt?
heat
What is the name of the process that causes ice to melt?
Application of heat makes ice melt, so global warming makes lots of ice melt.
What gas causes the ice to melt?
Gas does not directly cause Ice to melt. However if you are talking about glaciers then the gas Carbon Dioxide (CO2) causes the earths atmosphere to heat up (because it traps more of the Sun's heat) and this causes glaciers to melt - because the Earths climate is hotter.
