Why should an ohmmeter never be used on an energized circuit?
Because an ohmmeter works by putting a potential difference (voltage) across a load and measuring the resulting current (the current will be inversely proportionate to the resistance). In a live circuit there is already current flowing through the load so (at best) the reading will be inaccurate, at worst the meter will be damaged.
The electrical meter that should be connected in series with a live circuit is?
ammeter
How do you correctly test if a circuit is not live?
Use a multimeter and test if there is a voltage drop or current over the wire circuit.
What do I need to be able to qualify for a home repair grant?
It depends on which country you live in as to where you apply; in the United States you should look into the Department of Housing and Urban Development.
What are the approximations of open circuit and short circuit tests?
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
What happen ohmmeter hook up to a live circuit?
Depending on the voltage, make sure to be safe, but I don't think that it is too bad, although it does depend on the circuit

What wire in a circuit should contain the fuse?
The live wire
Can you measure ohms from a live 115v AC outlet?
No, the circuit should not be energized when checking the resistance of a circuit.

ammeter
What should be kept handy in case of there is a short circuit?
A safety obeserver who has a wooden object to pull you from the live circuit. They must be trained in CPR and know where the circuit breakers are to deactivate the dangerous circuit in case of a mishap.
What prevents you from receiving an electric shock?
Not touching a live conductive part of a circuit is a great way to prevent you from receiving an electrical shock! Along with this the circuit breaker should trip if there is a fault on the circuit, or a GFCI if there is no ground in the circuit
currently live in an apartment that accepts section eight how do i apply for assistance?
You should call your local housing authority to apply for section 8.
Will a rcd detect live to neutral fault?
No. An RCD operates by detecting fault currents on the circuit protective conductors(earth). An MCB(mini trip) should operate with a live to neutral fault(over-heating the circuit).
Can one apply for section 8 before a baby is born?
Yes people who are pregnant should apply especially if your family not helping and you still live with your family
Why should a polarity test be conducted out on a lighting circuit?
to make sure the protection device such as fuse are connected at the live part
Why should phase and neutral wire be put together in the metal conduit?
to prevent live conduit in case of short circuit
