What else can I help you with?
What will happen if 110 vac motor connected with 230 vac?
It will burn due excess current .
What happens to a motor that runs on 230 VAC is accidentally connected to a 440 VAC supply?
It will overheat, probably even on no-load. It might blow the circuit breaker or start producing smoke.
What is the maximum voltage rating for the equipment that can be safely operated with a power supply of 230 VAC?
The maximum voltage rating for equipment that can be safely operated with a power supply of 230 VAC is typically around 250 volts.
A typical light bulb in your house is rated 60 W which means that the bulb dissipates 60 W when connected to a DC voltage of 110 V What is the currrent?
P=VI 60W = 110V x I I=0.54* A Hopefully in your house you are connected to 110 VAC and not DC. Same answer as above applies.
Is an airconditioning unit labeled to run on 208 vac to 230 vac ok to run on 240 vac?
yes, UL listing requires them to work with tolerance of 10% over equipment voltage
How many watts does a CFL bulb use?
The answer to this is country-specific. In the United States: Residential 120 VAC. Commercial also uses 277 VAC Elsewhere in the world: 220 volts to 260 volts, most frequently 230-240 volts AC.
Why do you use 240 volt supply in the UK?
They don't. The UK uses 230 VAC 50 Hz.
Can you use 120 volt bulb in 130 volt socket?
All other things being equal, an incandescent light should not "flicker" whether it is connected to 120 or 130 VAC.
Is a 2 pole 30 amp circuit breaker equivalent to two single pole 30 amp circuit breakers?
Yes and no. Your electric panel has two bus bars. Each supplies 120 VAC. If you measure the voltage across these two buses you get 230-240 VAC. The buses are staggered top to bottom such that each breaker, top to bottom, alternates which of the buses they connect to. A 2-pole breaker would typically be use for 230-240 VAC service, but could be used for two 120 VAC circuits. However, in the latter case if either of the 120 VAC circuits tripped, both would trip. In the case of two single pole breakers, it would depend if they were connected to each bus or the same bus. However if used for a 230-240 VAC service you would want both to trip if either side tripped. This is done by joining together the handles of each breaker stacked on above the other in panel.
You have two devices that are rated at 230 VAC single ph and your supply voltage is 480 VAC 3 ph you need a 480 VAC 3 phase to 230 VAC three phase xfrmer how do you calculate the xfrmer size?
The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.
What is the voltage of line voltage?
It varies from country to country. In the USA it is 110 volts, in the UK it 230 volts +/- 10%/6%. In practise in the UK it is 240s volt +/- 6%, the slightly odd looking specification allows harmonisation with rest of Europe. In all these cases, the mains voltage is supplied AC (alternating current) and the voltage is given as root mean square (RMS). The peak voltage in the UK is 384 volts.
How many amps will a 230 vac 3500 watts heater draw?
Since power = voltage * current we have current=power/voltage so 3500 watts/230 volts = about 15.218 amperes in a heater using a resistance to generate heat. This should be valid even though the "230 vac" indicates that it is an AC circuit and not a DC circuit.
