Assuming a circuit breaker is also installed, then you will have a phase-to-ground fault, or a dead short. This will cause the current draw to spike and extreme heat to be created, which will hopefully trip the breaker, which will stop the current flow. If no breaker or fuse is used, then the wires will eventually catch fire from the extreme heat.

What phase changes happen to dry ice?
Sublimation: from solid directly to gas.
What will happen to phase angle if the the value of capacitor is increase?
in a series RC circuit phase angle is directly proportional to the capacitance
When connecting two alternators in parallel do the two voltages have to be in phase or directly out of phase?
They must be precisely in phase. If connected out of phase current would flow uncontrollably between the two alternators as a short circuit.
In a 4 wire delta connected system what does the orange wire mean?
High or "wild" leg phase to ground.
What is the difference between neutral point and earthing?
Earthing point is where conductor is directly connected to ground and its potential is always zero. Neutral is a return path in single phase system and in three phase system Neutral point will have zero potential if all the loads are balanced in the system. In un balanced three phase system even neutral point will have some potential
How do you find phase and neutral in the circuit?
Neutral will be closest to protective earth ground. In the US, neutral is white. we can check using tester ,when tester is connected to phase only lamp of the tester glows and when it is connected to the nuetral the lamp does not glow. another method is, connect the voltmeter to any one of the terminal and ground if the voltmeter shows 110v 0r 220v then it is phase and the other is nuetral.
When is a motor in star or delta connection?
Star (or wye) connection is where each of the three phases has a fourth conductor, neutral, as its current return. Current flow in this configuration is phase to neutral, which is also grounded back at the distribution center. There will be five total connections, phase A, B, and C, neutral, and (protective earth) ground. Delta connection is where each of the three phases uses the prior phase as its current return. Current flow in this configuration is phase to phase, and there is no neutral, though there is still a ground. There will be four total connections, phase A, B, and C, and (protective earth) ground.
What will happen if 2 phase load is connected to generator?
There is no such thing as a two phase load any more. Any two legs from a three phase system are classed as single phase. If this single phase load is connected across the generator it will induce an imbalance in the output voltages of the generator. This is one reason that single phase loads on a three phase generator should be shifted around to find the best possible balance.
What are white black and green colors represent on electrical wires?
In the US, the common usage of these colors is: BLACK: Hot - connected to one phase of the service AC. WHITE: Connected to the Neutral of the service AC. GREEN: Connected to the GROUND bus at the service entrance. At the service entrance, the GROUND and the NEUTRAL bus are connected together.
What will happen if single phase load is connected to three phase circuit?
To obtain a single-phase supply from a three-phase supply, the single-phase load must be connected either (a) between any pair of line conductors, or (b) between any line conductor and the neutral conductor. Of course, the voltage obtained from either of these connections must match the voltage rating of the load.
When trouble shooting a single pahse 208 volt hid ballast with your voltmeter you read 120 volts to ground on each phase wire but 0 volts across the phase wires what is wrong?
Sounds like both phase wires are connected to the same phase.
Are both 110V buses in phase?
The two 110V buses are 180 degrees out of phase. This is known as 120/240 split phase power, with the center point called neutral and connected to (protective earth) ground back at the distribution panel.
