This is not a simple question. If you intend to run the full 100A and want to use 2core and earth pvc cable then you need 50mm squared cross section conductors BUT if the cable is long you need to consider the voltage drop and may need a larger cross section cable. If yor want to run armoured cable, you can use 25mm squared conductors,but again you must take length into consideration

SOURCE: Electrical cable size requirement

This is an answer to your question only. The safest thing to do is hire an electrician to do it. There may be factors you don't recgonize that a skilled eye would pick up on.

The proper size wire is #4 copper or #3 Aluminum. THHN is the most common and most versatile type in conduit. a #6 ground wire is ok. Stranded pulls a lot easier than solid and do yourself a favor and buy some wire pulling lubricant just in case.
Make sure to obey all manufacturer's instructions. If you use aluminum make sure to place anti-oxidation compound or Nolox on your lugs in the panel. Please write back with anymore questions.

BUFFALO TOOLS 2000 WATT GENERATOR 12 VOLT OUTPUT BUT NO AMPS WILL NOT EVEN LIGHT A 12 VOLT TEST LIGHT BUT VOLT METER READS 12 V.D.C. WHAT IS WRONG ? PLEASE HELP.LABEL SAYS FOR 12 VOLT BATTERY CHARGING

have the voltage regulator system checked
in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put
that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board
there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

I HAVE DOMETIC DUO-THERM PENGUIN ROOF AIR CONDITIONING ON RV. THE UNIT WILL RUN WHEN PLUGGED INTO ELECTRICITY BUT WHEN GENERATOR POWERED THE AC UNIT KILLS THE GENERATOR ENGINE. WHAT COULD IT BE?

What size & type generator? On start up the AC unit can draw as much as 17-18 amps in some cases, and if your generator is not designed for a quick draw like that it will die.

Honda eu3000is generator surges

Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

I'm dumb. Can I hook an inverater to my generator and produce more enegry than my generator produces???

Please understand that the generator produces power from fuel with an engine wheras the invertor is one which genrerates power from a stored battery using the principle of frequency switching a DC source to induct and produce AC.
Now you can have an uninterupted power supply setting with the invertor backed up by the generator so that when the battery voltage goes down you can start and charge the invertor and also supply the extra energy .
the ratings of both must also be considered.

Will it be okay to connect a 110 volt laptop to a 220 volt LCD projector?

What voltage is your mains supply?
The laptop's adapter should be a multi-voltage type 110 to 240 volts input.
If your mains is 110 volts AC then the 220 volt AC LCD projector won't work unless you connect it to a step up transformer (110 to 220 volt transformer).
If your mains supply is 220 or 240 volts then both the laptop and the LCD projector will work without any problems.

I have an old mastercraft 110 volt ac stick welder model 110-104 have not used it for years have lost the instruction manual plate on the machine says primary voltage is 115 and primary amperage is 26.6...

35 amp should do nicely however make sure the mains cable is of the correct size, better still, get a qualified Electricion to install it.
Usualy 30amp could be used but using 35amp gives you some reserve

Run ac off of generator.

you need to use a volt meter and test which lead from the 4 wire output of the generator a 220 v is coming out.

the round center prong of the ac is its ground and should not be connected to any live power. it could be left unused.

tnx 4 using fixya,
