I need to start two motors on one 15 amp circuit. Will this prevent surge overload during startup by delaying one motor?

Define two motors.i.e., are they a tool and a dust collector, or two tools and a dust collector?To answer the delay question - yes, there is about a one second delay.I use a multi-outlet receptacle plugged into the tool outlet on the unit to activate the switch from several tools.Saves having to buy all the whiz bang stuff they offer. Everything works fine and I never forget to turn the dust collector on and off.

No. The system has two cords and you need to plug each into a separate line with its own 15 or 20 amp breaker. When I start my saw my vacume starts at the same time. when I shut off the saw my vacume runs for 7 seconds more.

The Vac does have a one or two sec delay before it kicks in. If it is long enough for the spike of the motor draw I am not sure.

No I wired both fans on....it was designedb for one...but I made two work. ..I just put a 20 amp fuse to prevent spikes in voltage

I have had my compressor on a 15A circuit for over a year and never tripped a breaker. Just keep in mind, that could change with what else you have running on that circuit. I don't think you will have any problems under normal usage.

Yes. So far my pull start has worked with one pull. Two pulls if the motor is cold. I've seldom used the electric start so far.

absolutely. The breakers prevent from overloading the circuit ONLY. This device protects against surges, high voltage, low voltage, open neutrals or grounds, etc. Small price to pay to save several thousands worth of electrical devices

you are running on a 12 volt system I use 15 amp fuses, but I check my draw and output accordingly and don't push more than I need or run more circuits and have switches, like 6 flood lights and a separate circuit for appliances/tools, depends on your 12 volt battery, a trolling motor steady draw or a faster high output for tools with a short draw.

Yes it can start a refrigerator or furnace blower (depends on HP of blower) I use it for two pumps on hot water furnace but they have low hp and have used it on the refrigerator. The length of time depends on battery strength more than surge. If not sure check your breaker this unit will handle abut 25 amps. watts/ 120 equals amps. So if breaker is a 20 amp it should handle it.

No, but there is typically no need. A surge protector anywhere on the circuit protects that entire circuit. So unless you have the duplex spilt into two circuits (common on newer washer and dryer outlets) there will be no need for two in the same outlet.

Electric motors are rated at sustained load (greater than 60 seconds), so on start-up the motor can draw more than double the rated load. I believe that the initial start would exceed the load rating for the inverter. The sustained load (running load) of the vac is approx 600 watts, so the starting load could be higher than 1200 watts for a short period of time (a second or two). I believe that it would overload the inverter. I would look of a 1500 watt inverter for that type of load.

Depends a lot on our house service distance etc. Short answer it can work but you probably need to use a 20A circuit minimum to run safely. For starters the fuse size for a 1HP with 16 full load amp is 20A (16A*1.25). This allows the motor to start with nomnal load without tripping the breaker. The longer the cable the further away you are from your utility transformer the more likely you will trip the fuse as the voltage drops (which increases the amperage)

Yes, I have mine starting a 110 motor. The switch is rated at 12 amps, so check the rating first on your motor to make sure it isn't pulling more than 12 amps.

Hello Peggy, If you Plan to use a load that surges to the 3,000 watt rating then you must use a 250 amp fuse or resettable circuit breaker for the Input side. This unit works well up to 1,000 watts It does not perform well on large start up motors like a Vacuum cleaner. I use this unit for small loads that require a pure sine wave. Mike

I would be a little hesitant as most motors present an inductive load which creates a high peak current at startup which could damage the internal relay. Look for a unit specifically noted as ok for inductive loads.

The maximum start up amps would be 15 - according to the plug. Although it probably uses only 8 amps. When the compressor is running about 3-4 amps according to our electrician.

Generally most inverters are able to handle such start up amperage increase for 10 seconds. That surge is typically double the rating...always good to check out all specs on these type of items, Keep in mind I'm speaking in typical application...hope this helps!

I have 4 of them on one circuit and one actually starts slower than the others, but only slightly. I would think up to 1 second delay would still be in the scope of normal operation.

Yes, But it would be one tiny motor. You must stay within the parameters of the power supply.
