What else can I help you with?
A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.8 106 N. For safety the cable must support twice that load.?
To ensure safety, the cable must be able to support a load of at least twice the maximum expected load of 1.8 x 10^6 N, which totals 3.6 x 10^6 N. This safety factor accounts for potential additional stresses and ensures that the cable can handle unexpected loads without breaking. Therefore, the cable must be designed and tested to safely handle this increased load capacity.
How do you convert volts to mva?
Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!
What is the voltage drop on 200 mtrs of 10 mm swa cable?
To calculate the voltage drop on 200 meters of 10 mm² steel wire armoured (SWA) cable, you need to know the load current and the resistivity of the cable material. As a rough estimate, the voltage drop for 10 mm² copper cable is approximately 2.5 mV/A/m. For a 200 m run, the drop would be calculated as 200 m x load current x 2.5 mV/A/m. For more precise calculations, please provide the load current.
What the ampere rating for the isolator for 3 phase water heater of 10 mm2 cables?
The ampere rating for the isolator for a 3-phase water heater using 10 mm² cables typically depends on the load current and local electrical codes. Generally, 10 mm² copper cables can handle around 40-50 amps, depending on the installation conditions (like ambient temperature and cable bundling). Therefore, an isolator rated for at least 40-50 amps would be appropriate, but it’s advisable to consult local regulations and the specific equipment specifications for precise requirements.
What is ampere rating of a fuse used to protect a 5.5 mm squared conductor?
The equivalent mm2 cross-sectional area of a 5.26 mm2 conductor is a # 10 AWG conductor. A # 10 AWG conductor size is protected by a 30 amp fuse.

What size cable is used for house wiring?
Copper SE cable gauge 00 from the meter socket to the breaker panel for a 200A service. Then 8, 10, 12, and 14 gauge wire depending on the load.

What happnens when a circuit is ''overloaded''?
When a circuit is overloaded, this "only" tells you that the load is greater than the design of the circuit justifies/defines as alright.We can have several manufacturers producing the same "circuit" and all of them may have slightly different "design" limitations.Example 1:A specific cable may be specified to safely provide 5 Ampere at 120 Vacyou may have 120 Vac at the beginning of the cable and after 100 yards, you might only get 115 Vac. 5 Vac is lost in the cable and is dissipated as heat. 5volt times 5 Amp = 25 Watt of heat to the cable.When this 5A limit is surpassed, ie you run 6 Ampere load on a 5 Ampere design, then the voltage will drop more. As a result, the cable will heat up more. As the cable heats up, the insulation might begin to melt. In worst case scenario this might cause a fire.Example 2:A long cable running 120 Vac at a load of 5 Ampere (or more) may have too much of a voltage drop for your equipment to run properly. This might cause equipment to malfunction or not work as well as intended.Note:Different countries have slightly different regulations regarding electrical wiring's. A cable designed for 120Vac in one country may qualify for 235Vac in another country. It may be ok for 5 Ampere load 120Vac in one country but 6 Ampere load in another country. Most cables are designed so that a little bit of overload is within safe limits.The longer the cables are, the more voltage drop and the more effect is lost in the cable. Long cables should not be overloaded, where as really short wires do not always pose as a risk even with 50% overload. (Generally less than 10 yards of cable).Stay protected though, and do not work cheaper "overloading" solutions in your house.A:An overload is when to much load is put on a circuit (too many lights or plug and cord connected loads, or motors working to hard), when this happens either the overcurrent protection device (fuse or circuit breaker) will open or in the case of motors an overload device will open the circuit. If these protective devices do not open the circuit properly the wires (or motor) will overheat and start a fire. The ampacity of a cable is rated lower than what the cable can actual carry before it fails, this is a built in safety that allows the protection devices time to operate properly.

Can you put 10-3 UF cable on a 50 amp circuit breaker?
A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. The only time that a breaker larger that the load maximum capacity can used is in motor connections. A breaker can be used sized at 250% of the motor's full load amperage. In this case a 50 amp breaker can be used on a #10 conductor if the motor's full load amps falls within the amperage's of 20 - 22 amps.
If 2kw generator is supplied to 10 ampere load how much will be its power factor?
The 10 A in the load includes the real power and the reactive power, if it is a single phase 120 V generator it can supply 16.67 A; that means a 2000 KW load at a power factor of 1.00, of for example a 1600 W load at a power factor of 0.80, in both cases the output current of the generator will be 16.67 Ampers, it is the same with the 10 A load, the power factor is included in the supplied current.Rosa María Valdespino.
