User questions & answers

Question:	Where can I download the user manual? The link on your product page is not working
Answer:	Mine came with a user manual such as it was. Take a few minutes and look on YouTube;it will be explanatory quickly! Good luck!
Question:	Will this meter read the wattage im putting back into the grid
Answer:	No.
Question:	How do you reset the usage? I don't need to reset the cost Kw/h, just the running totals
Answer:	Hello, this usage will be reset all, and then you could set the cost again, if you have any problem when reset, please tell us the details, you could send the email to [email protected], we will be surely responsible to this problem. thanks
Question:	Does it for remote by a computer or cell phone?will it work with 220v
Answer:	Negative. Most of these devices are rated up to 1875 watts. That's 125 volts times 15 amps. If your electrical service panel is up to code, the 15 amp breakers in it should flip off at 1440 watts. That's 80% of 1800 watts (120 volts times 15 amps). I have one window unit wired for 20 amps...that's 1920 watts safely. I have used these devices with my 20 amp outlets and but please don't make a habit of using it continuously, it will get hot and potentially start a fire. There are 220V meters out there but I'm not familiar with any of them. Take care!
Question:	Is this model 220v (Non US) AC compatible? If not, which model is? Thanks in advance
Answer:	This is a 120-volt meter. I recommend that if you want a plugin meter than can handle 240 volts you look one for the appropriate electrical receptacle on the front. This one clearly has a standard 120-vold outlet receptacle.
Question:	does this work on 220v 60hz house outlet
Answer:	According to product specifications Line Frequency range is 47.0 - 63 HZ. If your outlet is configured to accept the P4460 you should be able to use it. Before you buy you may want to ask the manufacturer this question.
Question:	Can it be set for a period of time (such as 24 hours) and record usage only then
Answer:	Yes, this records the total power used by the device whether it is on or off or any mix. You just need to go to the screen kwh used. record the beginning # and at the end of time period (say 24 hours) record the end #. that is how many kwh it used. I used several of these for months to record the A/C use in our shared apt and paid the landlord for the a/c used so they don't complain about my electricity used. great device. now however, my apt has a 20a a/c wall unit. while you could get converter to regular 3 prong, not sure if this unit will go to 20 amps.Others who said no are simply ignorant of this devices menu. It ALSo shows, when on watts menu, the watts used when a device is running, or is off. so you can see how much your a/c or toaster oven or giant screen tv uses when on, or off.It also keeps the power kilowatt hours used even if unplugged or power goes out in its internal memory. so you can simply record the kilowatt hours at the begin of a month, then at the end of the month, subtract and multiply by your cost of electricity for the total $ / month the device uses.The dork who was our landlord at the time thought his electric water heater for tea was less expensive to use than nuking a cup of water for a minute to heat it up in the microwave. popped this device on it and they were almost identical in total power used to heat a cup of water.The same idiot who was complaining about this left his rear projection tv on when he wasn't around, and they use alot more electricity than today's flat panel screens.If you want to record the power usage of some device over time, you'll want to plug this device into a short extension cord. if you plug it directly into the wall then you have to lie down on the floor to read the kilowatt readings. I just put the readings into a spreadsheet when I was recording monthly electricity usage.
Question:	To how many decimal places does this one display for Watts
Answer:	This EZ model does NOT display how many Watts you device is pulling... It displays how may kwh have been used thus far, to the 1/10th decimal place. So, when you first plug something in is shows ZERO, since not enough time has passed to show kwh used yet. This is a HUGE feature left off this device. For me, I want to plug something in to a meter like this and be able to instantly see how many Watts the device uses, and this EZ meter version does not do that.

Empowers You to Save Hundreds on Electric Bills

Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt, and it will assess how efficient they really are. The large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring voltage, line frequency, and power factor. Now you will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. Kill A Watt can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 amps maximum, 125 VAC maximum.

Find Out How Much Electricity You're Using

The U.S Department of Energy reports that 20% of our electric bills come from items that are left plugged in when they are not in use, or items that are in standby mode. With the Kill A Watt P4400 we can monitor the energy eaters in our homes and cut down our electric bills at the same time. Plug whatever item you want into the device and it will tell you the efficiency of that item by displaying the kilowatt per hour. This device will help you determine which items are costing you the most to run. The Kill A Watt also calculates voltage, line frequency, current, and power factor. You can calculate your electric bill before you even receive it from the electric company.



Test The Quality of Your Home's Power



But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.

User questions & answers

Question:	Hi, is this unit able to capture peak current draw? I want to see if my audio amplifier ever gets close to tripping my breaker
Answer:	This will only plug into a 120 VAC outlet. The standard 120 VAC outlet in almost all homes is only rated 15A continuous duty, but can take more for a second like when a room air conditioner compressor starts up. This is probably following those same rules. If the wiring is 12 gauge or thicker, it can be hooked to a 20 amp breaker even though all of the outlets in the average house are rated 15A, at least in most states. The reality of the matter is that wiring and outlets can always take somewhat more than the ratings and everything is oversized for safety. But is is always considered unsafe to plug in any device that uses more than 15 amps into a typical house outlet. An exception is commercial outlets that fit both home devices and heavier duty commercial device plugs and those outlets are usually rated at 20 amp. Those outlets are more common in businesses and uncommon in homes. An air conditioner or commercial refrigerator that uses more than about 10 continuous amps will normally be a 240 volt appliance and require different type of outlet designed for 240 volts, same is true of typical electric clothes dryer and this device would not adapt to those.
Question:	Will this work with two prong (non-grounded) outlets
Answer:	This device, the P4400, will reset all of its timed measurement values to zero if power is lost or the device is unplugged. The P4460 has "non volatile" memory, using a battery to provide the necessary voltage to power the (S)RAM memory, which means that it will not lose the data if power to the 4460 is lost. The P4460 also will let you input the cost per KWH from your provider to calculate the cost to operate the appliance over a week, month and year (assuming that your use is the same during the extrapolated period as it was during the measurement period). For me the data retention feature is well worth the extra $4 since I want to keep track of the energy used by a window air conditioner which will vary by the outdoor temperature, the sun hitting the building, the humidity, etc.
Question:	most of my outlets are 20 amps or more, the killawatt is only 15 amps does that make a difference in calculations, the garage is 40 amp
Answer:	Hello, the correct wire is typically referred to as 10/3 with ground, but yes 10/4 would be the correct amount of wires. Reliance Controls videos have the 10/3 with ground used in install videos. Any other video done by others may not have the correct wire.
Question:	what is the difference between the p4400 and the p
Answer:	Hello and thanks for your question! The PB30 inlet box is just a plug for a generator cord in an outdoor rated enclosure. It is used to connect a generator cord and then bring the wiring into a building to connect to what should be a transfer switch or device. The wiring from the PB30 brought inside doesn’t have to connect to a transfer switch for the power to be utilized, but every state law requires a transfer device to connect generator power to. Hope this helps!

Question:	will this record the average power consumption over time? if i needed to record the average power of two devices over like 8 hours can I do that
Answer:	Maybe. About 25 ft was the max range for me. I got a 15 ft usb cable extension and ran the reciever box out under the bed of my truck which got me in range of the tire sensors.
Question:	Is this 10a pr outlet (20a total) or 10a total (5 per outlet). the description says max rated current 10a so it is a little confusing? please clarity
Answer:	I don’t know to be exact, but probably every minute or so, and it does it in cycles, so one wheel at a time about every 30 seconds

User questions & answers

Question:	Does it track track the usage of the whole building or just whats connected to it
Answer:	Yes you can. Once you switch off the power to the outlet, the lights will turn off. You can also set run times 4,6 or8 hours to turn off If left on auto, lights will turn off at dawn.
Question:	Can the tool reverse direction to remove screws
Answer:	Actually there is a reason this can happen. If one of the landscape lights is pointed at the unit, the light from it will fool the photocell into thinking it's daytime/sunrise/etc and turn the lights off. Now it's dark and the photocell thinks it's night time again and turns the lights back on which fools the photocell again... on/off/on/off etc until this situation is remedied. Many units are returned as faulty because of this and bad advice as to the cause.
Question:	Is this drill size and weight well for use by a woman
Answer:	Life Time
Question:	What is weight of this screwdriver
Answer:	I live in Tucson AZ and summer temperatures approach 115 degrees Fahrenheit and so far there has been no difficulty. My unit is in it's 4th year of service.
Question:	Does this screwdriver set come with a plug
Answer:	I have 2 "runs" of about 60' each with 12 gauge wire and 8 10 watt LEDs lights, so not sure about using just one tap.Should be OK, especially if using LEDs and 12 gauge wire.Somewhere I found a "calculator" for landscape lights that allows you to input wire size, light wattage, and length of run to tell you how much "loss"you would have.Try Google

Empowers You to Save Hundreds on Electric Bills

Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the BN-LINK Energy Meter, and it will assess how efficient they really are. The large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring voltage, line frequency, and power factor. Now you will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. BN-LINK Energy Meter can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in.
