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
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 causes the rock in the mantle at divergent boundaries to melt?
The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
What from lemon juice causes ice to melt the fastest?
The rime
What causes air to be trapped in a mold?
melt flow patteren.
Can a melt down be stopped?
Yes by rewinding the causes that encourage melt down ; Carbon economy in case of global warming .
What is the name of the process that causes ice to melt?
The process that causes ice to melt is called melting. It occurs when heat energy is transferred to the ice, breaking its molecular bonds and causing it to change from a solid to a liquid state.
What gas causes the ice to melt?
The main gas that causes ice to melt is carbon dioxide. When carbon dioxide levels increase in the atmosphere, it leads to a warming effect on the Earth's surface, which in turn accelerates the melting of ice and glaciers.
What causes ice on a pond to melt?
Sunlight melts it away! The rays the sun casts is enough to melt ice. also the season's are changing
