Re: Im buying a gen set for my house
There shouold be a model/serial plate on the inside of the unit, the wattage/amp rating should be listed on it, if not there is a pretty cool gadget called "kill-a-watt"--- google it or find it on newegg.com for less then $20 you can check the wattage of all /anythikng you have plugged into your home
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

ac units are 2000 watts minimum, washing machines are 1500 watts minimum, microwave is what is on the plate and start at 650 watts but most are 2000 watts
the 2400 is the peak out put for start up of fridge , washer etc and the running wattage will be 2000 watts or less ( duty cycle )
to run more than one of the nominated items at once you will be needing a 5500 to-6500 watts unit
they handle a start up surge of 6500 watts ( larger one) and will comfortably handle 5500 watts run full load
it works like this , the plate on the gen set is the surge short time load capacity of the genset and not the duty load which is 500 to 750 watts less than that plate wattage
for example your 2400 is is surge rated at 2400 watts but duty load is less than the 2000 watts
many people make the mistake of buying a gen set that looks big enough but do not calculate the maximum load capable on being put on the gen set
fully loaded uses more fuel /hr
wears out faster
has power surges as the extra load cuts in and the motor struggles to get back to required rpms for voltage and cycles
will not cover extras like lights ,
a much large gen set will take it all in it's stride , no power surges, better economy, less stress
talk with an electrician , do your maths on everything you wish to run and that which you forgot about then add 1000 watts to the duty cycle and that will be close to the gen set you require
what is the wattage of the coffee pot and what is the wattage of the genset
if they are the same then the overload of the gen set has cut in
the gen set has to be at least twice any wattage of what is connected
other than that take it in for a proper diagnosis and quote
find the decal on the fridge( side , back inside ) that has the specifications on it
it will show wattage usage for the motor , volts required and phase/cycle requirement
now for example --if the wattage is 750 watts , then the start up wattage will be almost double for a few seconds until the motor builds up speed
so the generator size will be 2000watts continuous
that is an example
however understand this , if you get a genset that just covers the watts required , it will use a lot more fuel under full load than a gen set that has a capacity of say 4 times the requirement
next point-- gensets that just do the job will struggle on compressor start up and that can cause problems on modern fridges power boards where as a larger genset will hardly notice the load of a starting compressor
Lastly always use a surge protection board before the fridge lead as gen sets can "hunt " and produce power surges which can damage a board of the fridge
In reality if you have an outage,-- mostly at night,-- I would consider a gen set of 6500 watts capacity as that will handle fridge , freezer and house lights
I run a scorpion 6.5 kw get set connected to the house by a three way switch and a caravan plug in the meter board and that runs 2 fridges , freezer , lights and one small plate on the electric stove and 20 liter fuel tank lasts up to 6 hours running
and no it is not an inverter type so the cost of the unit is around $1200.00 aud compared to an inverter type which is more than double that price
plenty of food for thought so that you make an informed decision
not really easier to make an adapter for the twist lock so it can be plugged in also be sure of your wattage /amp set up this is a small generator will do quite a few things but not a whole house hook up the ones on the bottom are your 220v and the top is 120v
the wattage is on the plate attached to the drill and will still be the same as before you attach a step down transformer to get to the correct voltage
get a step down transformer that has a large wattage rating for 120 volts ( say 1200 watts ) as most 1/2 drills are 750 -1000 watts )
the wattage is for the rated current through the transformer and if the drill is of low wattage , it just gives the transformer a greater degree of serviceability in the duty cycle
talk with an accredited electrician as there will have to be a special relay/ breaker in the fuse board of the house
the problem is that your genset cannot be running when utility power comes back on as it will destroy the genset
the electrician can wire the board so that when utility power is available the gen set can be started but not connected to the house
when the utiltiy power fails the relay switches over to the gen set and allows it to start and power the house
when utiltiy power is restored the relay disconnects the gen set and reconnects to the utiltiy power supply
This is not a job for anyone except a fully qualified electrician
on the plate attached to the motor you will find several important items
one is the wattage of the motor
this is the maximum wattage that the motor uses when under load
the gen set will need to be at least 30% bigger than that figure
next there will the number of phases that the motor is
it will read as 1 ph or 3ph
If it is 1ph that is a single phase motor and will ru from a single phase gen set
however if it is 3ph you will need a 3ph gen set to run the motor
As most single phase motors are limited to around 5hp I would be very sure that the motor is not 3ph
specialist advice from an accredited electrician or electrical motor shop is recommended before buying a gen set. as if you need 3ph the gen sets become expensive.
950 watt is very small. Most electrical appliances need 1000watt to operate so if the vacuum cleaner is 1000watt then the gen set will trip. Check the drill as it is possibly 850watt which the gen set can handle. It all has to do with the wattage of the equipment you intend to run from the gen set
You can try running a heavier Gage or shorter cord to the genarator. If that's been done try useing a power suppley box commeing from your gen. not a surge protector this will have battries inside it, doing this will cutt down on electrical resistance. If those don't work you will need a bigger gen. The problem is the amprage is to low, one more thing, look in to a inline a/c compasitor
