You need to use a 2:1 ratio transformer, with a capacity (in volt amperes) to match the load you have in mind.

Any advantages in wiring a single speed pool pump 230V vs 115V electrician says cheaper to wire 115V?

Your electrician is correct on this. However, the pump is designed for 230V and will use less electricity, thus saving money if wired for 230V. Yeah, if you have to rewire for 230 V then it would be more expensive until your savings had consumed or offset the expense.


Will a 15A 115V air conditioner work properly in a 15A 230V air conditioner electrical outlet?

Absolutely not.


How many voltage does an air handler use?

residential usually 115v or 230v. Commercial could be 115, 208-230 or 460


Is 115 v good for home theater?

If you live in an area that uses 115V as the mains supply, then it's absolutely fine. Equipment sold in the area will be designed to operate on that voltage and there is no difference in performance between 115V equipment and 230V equipment.


How many volts does a computer monitor use?

from the wall it could be 115v ac, or in non American countries that use it 230v ac. internal voltages range from 12v dc, 5v dc, 3.3v dc.


Do i need to switch circuit breaker since i went from 115V well pump to 230V well pump it is also a higher HP pump but pressure is lower than before?

The 230v breaker is 2-pole, The 115v is only single-pole so YES you need a new breaker. DON'T use 2 single-pole breakers instead. The well pump will run to the pressure setting of the pressure switch controlling it, regardless of HP. The difference might be in the size of the pump in flow rating, I.E. a 1/2 HP pump rated at 10gpm @ 70 psi won't perform the same as a 3/4 HP pump rated at 20 gpm @ 50 psi. Check the pump curve and pressure switch setting. The pressure switch for the new pump will need both power leads connected to the switch (1 lead per contact set), not 1 wire as the 115v motor was.


What happens when a 230V dc series motor supplied by 230V ac?

1000w 24v dc is equal to how many watt in 230V AC?

The wattage would stay the same. It is the amperage that would change.


What happened if you connect 230V to secondary of transformer whose voltage rating is 230V to 18V?

if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
