Is the fuse really necessary for home sump pump use, nothing else? I have a 100aph battery I'll never exceed limits on. The ground wire connection on unit even if plugged into grounded receptacle?

I didn't install any additional fuses. I'm guessing the ground wire is there to protect the battery connection. It was easy for me to do it, so I did.

As far as I know, the fuse is to protect the wire running from the battery. Without a fuse, the wire could be overloaded, heat up and possible catch on fire. A fuse is not very expensive, definilty worth it for your safety. The fuse needs to be rated for the gauge wire that you are going to use. I have 0 gauge wire running from the battery with a 250 amp fuse. The fuse needs to be on the positive wire within 18 inches from the battery.

I have installed over 30 units and never used the ground connection. This goes to earth ground which is never near by the sump pumps. The fuses on the unit is to protect the electronics in the unit. Not sure what fuse you are referring. Sump pumps should be on their own circuit breaker. I never install a fuse from the battery to the unit. That is a direct connection.Good Luck,Rick

For a sump pump in your house its worth the $20 and stereo fuse to nit have a fire start in your house. It will trip first.

If it were just a sump pump I would say yes, but being a battery backup where everything is tied together I would say no? Not for sure though. The float on this is not the large ones that come with most sump pumps. There are two small floats that do not need to have that much water to rise them to set the pump off. For just regular sump pumps you have to google: PumpBiz. They are in Chicago and I have ordered all my pumps from them. Ask for Jeff Richmond. They have sold me countless 'switches' that act as a float but it uses a wire that when the water hits the wire it sets off a manual pump. You have to get this.

Mine is the 115V only. I used a CGFI cord and there is a ground tap on top. Some states require bonding of swimming pool and pump. Hope this helps.

All of the liquid is in front. It goes in the big hole and out the small one. The wiring is in back it is 12 volts and easy to wire. I used a single gang 110 volt new construction box and a light switch for 110 volt light. You need a real strong 12 volt service. Straight to the battery would be best. I think I've had my pump a couple of years now. I live full time in A RV and I use it about once a week. It's still going strong.

My pump did not come with any wiring. With the 1.5 HP motor you must use 14 AWG from the contactor to the pump motor. The 1.5 HP motor at 240 volts pulls 9.5 amps so you need 14 AWG wire. 14 AWG wire is good for 15 amps. This is recommended in the manual. The 14 AWG is good up to 100 ft from the contactor to the motor. If the distance is greater than 100 feet then you need 12AWG due to voltage drop.

yes willie...how do i do to replaced pump with low voltage pump. it's too strong pump. i have probllem with water flash out on floor. thanks you for asking.

Being a 1hp pump, the current draw is 6.5 amps. Make sure wiring should handle it. I would advise using a GFI outlet on it for shock protection should the motor windings short out (very rarely happens). That's the Engineer in me worrying about things. Good luck!

I would use one off the discharge of each pump, then into a "Y" connection to the outlet. Otherwise, you risk pumping through the other pump right back into the sump. Staggering the height of the pumps would prevent both pumps from coming on at the same time.

It would be possible to wire it to work for that but it will require a 24V power supply and a relay with a 24V coil and contacts rated for 120V A/C. Since you will be dealing with high voltage, it should be enclosed in an insulated or grounded enclosure. I'm not sure what you want to accomplish. I imagine that you have a 120VAC pump that filters the water and you are concerned about it discharging into the floor. In the event that happened, you would want it to shut off the pump. Is that correct?

It is complete. Install onto exit piping in your sump, and plug it in. It works. I also have an extra battery-powered backup pump-and-float-switch, but if you aren't too worried about whether you have sump pumping if there is a power failure, you don't need that extra stuff.

I'm not sure, but I would guess that they want a minimum of 100 volts while the pump is running. I just replaced my existing pump (which was larger) and plugged it into the existing receptacle. If the size of the pump is the same or smaller there certainly shouldn't be a problem. If you want to do the exercise, connect a voltmeter to a nearby plug on that circuit and observe the voltage while someone turns the pump on and off.

I bought this unit a few years back for a rental property. Here's what I can find.BASEMENT WATCHDOG BACK-UP SUMP PUMP SYSTEM Includes 1/3HP (2820 GPH at 10) A/C sump pump and Watchdog special emergency back-up sump pump (1730 GPH at 10) Pre-assembled for easy installation Compact footprint fits in any size sump pit Dual float switches provide dependable activation for each pump Controller sounds alarm if maintenance is needed Battery

I did. Just need to use a diode between 86 and 85 to keep the volts from killing fish. But I would use delay relay like (SRD-12VDC-SL-C NC Triggered Time Timer Delay Power Relay Module 12V DC). It keeps it from getting into that loop of the bottom of the container to the sump.

Yes...it just has a 110 outlet that you plug your sump pump into. The controller then plugs into the house outlet and then switches power to the pump when the float switch is activated.

So I put in a backup sump pump (liberty 24v marine battery kind), if my sensors or wiring fail. I mean, your bottom one is submerged in water, so why not the top wiring too. Same diffetence. Get a backup to be safe. Pumps fail. Power fails. Floats and electronic sensors fail. 500 is cheap insurance for a backup system. You can install it, trust me.

It uses a 200 AMP ANL Fuses. Make sure that the lead wires to the inverter are no longerthen 4 feet and are at least 2/0 (two aught) wire in thickness. Use two heavy duty marine gradebatteries in parallel maintaining a longer drain@ 12 volts.

Your float turns a switch on and off on or near the motor. If you can lock the switch in the on position (many options), and your pump runs full time, you can use this switch by plugging it into the outlet first and then plugging the sump line into the control. Directions aren't the best but mine still works. Good for up to 14 amps. I'm always cautious with low stock items. They could be returns but Amazon backs up their products.
