User questions & answers

Question:	Can I use it on a gas dryer that takes 30 Amps for a split second to start? I know it runs below 8 amps once started
Answer:	Its a crap shoot as to whether this meter can handle the surge current of start up. Maybe itll work once, twice, a few times. But eventually it WILL fail. Id recommend one of those add in power monitor displays with a split core transformer that is clamped around the input hot line to sense current. For example, a CrocSee CRS-022B. Much, much safer. And can sense up to 100A!
Question:	can be used connecting 220 Volts at 60 Hz
Answer:	Yes, this item is designed for 110-220v, 50-60hz, AC power.
Question:	Can you plug space heaters into it safely
Answer:	It depends, the max. wattage rating of the PN2000 is 1760w @110v or 2000w @125v (16 amps). As long as your space heater rating is lower than this, it should work. Most space heaters have a max. output of 1500W, so you should be good to go. Note: Due to the large start-up amps of space heater, though device has abilities to deal with it, we still recommend not to use the device near the max rated specs (in most cases, the true RMS Current will be around 15A) for a long time to avoid any unexpected damage or accident. And please kindly know that the inner and outer device material is fireproofing. If device is over used or exposure to excessive heat, it may cause a melt incident but it won't start a fire. Still, you need use this device carefully to avoid any fire hazard.
Question:	Does it tell you how much electricity has been used in 24 hours and the cost of usage
Answer:	Yes, it will give a total usage over any time period (loose power circuits will be fine, consumption kWh will be kept in memory). So you just need to let it run 24 hours and check the Electricity Consumption (EC). Regarding the cost of usage, you have to do the math. Here gives you an example: Let's say your billed KWH is 0.07 and the distribution charge is 0.04. Then the KWH charge $0.07 + distribution charge $0.04 = $0.11 per Kilowatt Hour(kWh) usage. So if your device is using total 2.4 kW-hrs(EC) per 24 hours (which is equal to 100 watts in one hour), then you are paying $0.11 per kWh * 2.4 kilowatts per day = $0.264 for each day of use. Hope this explains it better.

User questions & answers

Question:	how do I know if I need a 50A or 120A
Answer:	For normal usage 50 amps should be plenty. If you use it at 110v at 120amp would be > 13,000 watts i don’t know an appliance that would use that much power
Question:	Can this be used at the mains to monitor whole house consumption
Answer:	yes you can monitor the main line of up to 200 amps. 100 amp per leg. two sensors, 100 amps each. however, there is only one voltage input, so you won’t get perfect measurement. also, it is recommended that you connect the power to a separate breaker in the box (don’t double tap any existing breakers). that said, it does a good job. the app is limited, but it does mqtt connectivity. use it with something like home assistant or some other smart home product as data input.
Question:	When connect to 240vac (in the usa), where land the wires ? i see "l" line and "n" neutral. but 240v is line and line
Answer:	in us, use two ct’s. one for each 110v leg but there is only 1 voltage input. be aware.
Question:	how do I get a second CT
Answer:	get it online from the manufacturer

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

Product description

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. 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 energy meter,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 unit also calculates voltage, line frequency, current, and power factor. You can calculate your electric bill before you even receive it from the electric company.
