I would say that probably the fuse holder is loose, this would cause a voltage drop and result in heating of the fuse. Replace the fuse holder.

What is a difference between 3 phase and single phase?
AnswerA single-phase system has two conductors: a line and a neutral.A three-phase system has either three or four conductors. For a three-phase, three-wire, system the conductors are called line conductors. For a three-phase, four-wire, system there are three line conductor and a neutral conductor. In Europe, the three line conductors are coloured brown, black, and grey, and the neutral conductor is coloured blue.
Why you use only single phase and three phase supply?
Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.
Can you hook up only 2 of the 3 phase lines to a breaker switch to use as a on off switch for 3 phase paint booth motor?
In single phase applications, you have two wires. One of these is "hot", meaning it has an AC voltage applied to it. The other is not - it is directly tied to ground or the system neutral. In three phase power, all three wires are "hot", and use the other wires as the return path under balanced conditions. Because of this you cannot do what you are proposing and have a safe setup. Isolating only two of the three wires still leaves one "hot".
What is single phase outlet?
It is an outlet that has one hot wire, such as a household receptacle, or two hot wires, such as a dryer outlet (in the US). If the outlet has three hot wires, it would be called a 3-phase or polyphase outlet. These would normally be found only in an industrial setting.
Should there be voltage between ground and each hot of a three phase power system?
There are two types of connections in three phase systems. One is a delta connection where there is no connection to ground, so you should not get any voltage to ground. This is classed as a three phase three wire system. In this type of system any one of the phase wires could become grounded and no one be the wiser. Code requires that grounding lights be added to a delta system to visually show what the phase condition is in relationship to ground. The other type of system is a wye or star point connection. This is classed as a three phase four wire system. In this type of connection the coil ends are all joined together and grounded. You would have voltage between the phases and a lower voltage to ground. The voltage to ground would be the phase voltage divided by 1.73.Yes. If there is no voltage between a hot and a ground, either the hot isn't really a hot or the ground isn't really a ground.AnswerThere is always a potential difference between a line conductor and ground, regardless of whether it is a three-wire system or a four-wire system. This is due to the capacitance between line and ground.
Parts of oven toaster?
a hot plate,a oven area, and three nobs
What is mean by that a system is a three phase?
There are three "hot" conductors, all at voltage, and 120 degree phase shift apart from one another.
A three phrase circuit has how many hot wires?
Three wires carry the three phase energy.
What are the parts of a rice cooker?
The three main parts of an oven are the grill, hob and oven
How do you covert 120 volts to 208 volts?
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
How do you hook up a three phase welder?
Easy as one,two and three. There are four primary wires coming from you service panel.(provided you have three phase service) you can check by looking at the weather head on the roof. if it has three wires you have single phase but if it has four then you have three phase. the hot wires will be black,red and brown. the neutral will be white or green. the welder should have a manual that will give you the lead phase wire(most likely black to black) the other two hot wires can hook to any other hot wire. The neutral goes to the white or green and posts to the panel. If the welder has a switching power supply then you must have a three phase converter.
How hot is a oven?
Quite. It depends how hot you want it and what type of oven you have. For example if your oven is a NEFF oven it will go as hot as 275C. Hope this has helped :)
What is normal house current three wire single double or three phase?
Normal house current is two-phase, 240V. What comes into the house is two hots and a neutral. From hot to hot you get 240V and from either hot to neutral is 120V. In the electrical trade there are only single phase and three phase systems. The reason it is called single phase is that the primary connection on the high voltage side is one leg of a three phase system. This 3 PH system is usually about 12500 volts. On the primary side of the transformer, the connection is between one phase of the three phase system and ground usually in the area of 12,500/1.73 = 7225 volts. The secondary side of this transformer is 240 volts with a grounded center tap. As stated above this is where the 240, 120 voltages come from.
Why is neutral line needed in home electricity?
A fuse is NOT fitted in the neutral phase of single phase domestic power supply. The fuse is fitted in the LINE (also mistakenly called Live). If you have checked and found that the fuse is in the neutral, something is wrongly wired.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
