By asking this question you are probably not quite ready to take on this particular task. The correct answer to your question will depend on the exact location of the light fixture.
<><><>
If your bathroom light fixture has an outlet in it you will need to make sure that the entire bathroom's electrical circuits are protected by a GFCI circuit breaker. Many homes built before the 1980s have bathrooms which are not protected by a GFCI because the wiring code applicable back then did not require it.
If the old light has a built-in outlet you will not need to cap the outlet because it will be removed along with the lighting fixture.

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.
Volt-Amp gets its name from Ohm's law, where volts X amps = watts. You will commonly see it abreviated as VA. Also called apparent power. So, when we say volt-amps, we are alluding to a measurement of power. Strictly speaking, VA is not always EXACTLY the same as watts though. In a DC circuit, or an AC circuit where the load is non-reactive (purely resistive), volt-amps are exactly the same as watts. In an AC circuit where the load is reactive, current is not exactly in phase with the voltage, and watts (true power) will be lower than VA. For example, consider a standby power generator like you might buy for a building. It may be rated for 10,000 VA if it is feeding non-reactive loads, like electric heaters and incandescent lamps. BUT, the same generator may have a watt rating of only 8,500, meaning if it is powering a reactive load like motors, flourescent lamps or computers, it is limited to less than 10,000. The difference is called power-factor. In the example above, the power-factor would be 0.85. If you want to lean more (who doesnt?) do a google search for the following terms: true power apparent power power factor reactive power KVAR (kilovolt-amp reactive)
It is a measurement of total power. Very similar to watts. Volt-Amps is also known as VA. The formula is: VA = Volts * Amps
You may want to check your motor on the washing machine. It may have a bad short.
Can you hook up a 30amp breaker to a 20 amp outlet for an air conditioner?
STOP! DON'T EVEN THINK OF DOING THIS!
It is foolish, dangerous and probably illegal to "hook up a 30 Amp breaker" into a 20 Amp wiring circuit feeding a 20 Amp socket outlet.
Leave the present 20 Amp circuit alone!
Someone who knows what he or she is doing must run a new30 Amp circuit with the correct type of socket outlet , the correct size of wiring and the correct size of circuit breaker to provide a safe and legal supply for your 30 Amp Air Conditioner unit.

If you asked this question because you have no experience of working on the latest household power circuits and you hope to get enough information on this site to be able to do the job properly and safely, it is best to warn you not to rely on getting accurate information from this site about such a potentially dangerous subject.
By asking this question you probably aren't quite ready to take on this particular task.
Really, don't do this one yourself. Electricity is far too dangerous to handle if you don't already know your local Wiring Codes or Regulations or you have not been trained how to do this work.
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact location of the appliance you wish to hook up. If it is anywhere that is subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician.
For your safety and that of anyone else who may to use the appliance, ask a professional licensed electrician to advise you or to do the work for you.
ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING ON POWER MAINS OUTLETS

If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work
AND
always use an electricians test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.

A ballast can only burn out because it has been overloaded. It has nothing to do with needing a Ground wire!
There may be some other fault within the lighting fixture that is causing it to draw too much current, which would cause the ballast to burn out.
Or maybe the fluorescent lamp tube you are using needs a higher rated ballast unit than the ones you have installed? The fluorescent tube - or its packaging - should have some rating information on it, stating what size of ballast unit it needs to limit the lamp's current to its rated running Amps. If you cannot get any proper advice from a lighting store then its best to ask a licensed electrician to assist you.

What is the voltage of French national grid?
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
Materials used in constructing a full wave rectifier?
Full wave rectifiers consist of two (for a center-tapped transformer) or four (for a single-ended transformer) diodes connected such that as the polarity of the AC input changes, the diodes steer the current flow so the output polarity does not change. The output of a FW rectifier is pulsating DC, which is normally then filtered or smoothed with a capacitor.

What are form A form B and form C contacts?
These are contact arrangements that can be found on switches and relays. The form designation is fairly old and rarely used now. Form A: a single, normally open contact that closes upon actuation. Form B: same as A, except in reverse. A normally closed contact that opens. Form C: A form A contact connected to a form B. The Form C contact has three wires, NO (normally open), NC (normally closed) and C (common). Upon actuation, the NO contact closes (continuity from NO-C) and the NC contact opens (no continuity from NC-C). It is more common now to see the following designations: Forms A and B can also be referred to as single pole-single throw: SPST-NO = Form A SPST-NC = Form B and Form C can be referred to as single pole-double throw: SPDT = Form C
Do you need an adaptor in England?
No, you don't need to use any adaptors if you already live in England! That's only joking! You are probably asking: "If you travel to England from somewhere else, would you need to use an outlet adaptor to run small electrical appliances?" Some small appliances, such as electric shavers, mobile phone chargers, etc., are marked to run on a wide range of voltages, say from 110 Volts to 240 volts, and on 50 Hz as well as 60 Hz.
So, as long as you know your electrical things, which you want to take with you to England, were made to run on 230 Volts, 50Hz AC (the UK's standard household power) as well as on whatever voltage and frequency you normally use at home, you should be ok. However, the UK has socket outlets which are different to most of the rest of the world. So if you live in another country you probably will need to buy an international travel adaptor. Most international airports have shops which sell them. For more information please click on the Related Questions shown below.
What is the disadvantage of ac current?
Alternating current is very advantageous! If you have a need for more information please read some of the Related Questions shown below. If you wish, please ask a more detailed question giving a bit more information as to what you need to know and why. [Trying to answer this question as it is stated without having more information would be as hard as trying to answer questions like "What is the disadvantage of using water?" "What is the disadvantage of swimming?", etc.]
Do houses in Havana have electricity?
Yes. The information for Cuba is shown in the answers to the Related Links shown below.
What fuse do you need to run a 200 watt bulb with 230V?
The formula you are looking for is Amps = Watts divided by Volts. Once you find the amperage you can decide as to the size of a fuse you should use. Remember that fusing protects the conductors of the circuit and not the load of the circuit. A #14 wire is rated at 15 amps and can legally be loaded only to 12 amps.
Why do buildings and homes have lightning rods on top of them?
To conduct the electricity from the air to the ground, preventing a direct strike to the structure

How do you wire a 20 amp 115 volt outlet?
i) the asker is an adult who has no experience of how to extend household power wiring using a safe method which conforms with local wiring codes or regulations;
or
ii) the asker is a student who has to the question in some homework or in an exam paper.
An experienced electrician would not need to ask this question on this site.
This is a very serious subject because if you do something wrong in electric wiring, even a small mistake like putting one wire in the wrong place, it could kill you or someone else.
If this question has been asked by an adult, if you asked this question here because you don't already know enough - if anything - about household wiring to be able to do this job safely and you hope to get enough information on this site to tell you how to do the job properly and safely, the best advice anyone can give you is not to rely on getting accurate information on this site about such a potentially dangerous subject.
It is much better to call a licensed electrician to do this job for you. Correctly sized breakers would then be installed on your main panel (if necessary), the correct size of wiring and the correct kind of socket outlet would be used to do the job and an installation method would be used that is safe and which complies with the wiring codes or regulations in the locality where you live. (Town/State).
If this question has been asked by a student to help get a quick to a science homework question, or for an exam question, the best advice anyone can give you is to encourage you to go your local library and find some books on the subject, so you can learn about it properly and then write your own . That is the way to really learn stuff! It would also be very good experience for you to learn how to do basic research and to such questions by yourself.
the output voltage will be much larger than the input voltage
