Product Description
This Supco SPP E series electronic potential relay style hard start kit has a two-wire installation connection for starting motors. This electronic relay meets Original Equipment Manufacturer (OEM) requirements for relays to fit multiple applications. It has an instant re-start feature and a voltage-sensing capability. This relay has a back-up electronic timing circuit to protect the compressor can be used on permanent–split capacitor (PSC) and capacitor start induction run (CSIR) type compressors. This hard start electronic potential relay is Underwriter's Laboratories (UL) recognized and North American Technician Excellence (NATE) certified and is suitable for use in heating, air conditioning and refrigeration applications.
Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.

Supco SPP6E
By Delbert Brown
This little unit worked super well on my RV air conditioner. I was having trouble running my AC on a 3000 generator if the generator was set in economy mode; it would send the generator into overload. Everything work great now doesn't even dim lights anymore when the AC comes on, it now will start on a 15 amp household breaker without any problems. Very satisfied

In Maryland, we've been having an increasing number of blackouts due to bad weather. We already had a small 3500/4400w (continuous/peak) generator hooked into a 10 circuit transfer switch. When we installed that system, we decided not to consider powering the central air conditioner.Then a major heat wave combined with a REALLY bad weather, resulted in 100+ degree weather, half the state being blacked out for up to a week, and our decision to upgrade the generator to power the whole house hvac system.We're running a single phase (~240v) Trane XE1200 with a rating of 12 RLA and 65 LRA. Not realizing the importance of the AC unit's LRA value. We bought the biggest generator we could find sitting on a shelf at Lowes, a Generac Xg8000e 8000/10000w unit. Upgraded the generator side electrical wiring in the house from 10 gauge to 6 gauge. Fed the new wiring into a dedicated sub panel and piggy backed our orignal transfer switch panel off of the new subpanel. We put in a 20 amp dual pole circuit breaker into the new sub panel and feed that into a 30 amp, center-off Leviton 1288 a/off/b dual pole switch, to cleanly switch the ac between line power and generator power, the furnace blower motor was already wired into the original transfer switch panel.So, after upgrading the generator, supply wiring and power distribution... The ac wouldn't turn over. That's when we realized 65x240= 15600, we were at least 5600 watts short of the power needed to start up the AC, 12x240 = 2880 but we had more than enough power to sustain it, once it was started. We were prepared to exchange our Generac for the larger Gp175000e (17,500/26250w) unit...Then we read about Hard Start kits and their ability to deliver serious, yet brief jolts of current to an ac unit for easier startup. We ordered a Supco Ssp8e Electronic Potential Relay hard start kit. When I opened up the ac there seemed to be a hard start cap 5-2-1 style already there. Installed the supco in parallel with the existing start cap, across the herm and common connection of the main dual purpose cap.... No luck, still wouldn't start up under generator power.Then, I removed the old starter cap and just left the supco unit installed, across the herm and common connectors of the dual purpose cap and... Bingo(!)Ac started up and has been running properly all day. On a day when it's 105 degrees out side, we're at 76 degrees inside the house, under generator power. The temp did climb to 79 degrees while I did the hard start kit install but dropped back down within an hour or two.

An ac service person charged me over $200 for 15 minutes of work to replace a blown capacitor with this when my compressor would not start. Next Time, I'll do it my sself for around $20. Read the instructions or look for installation videos before use. Warning: You could get a shock, if you do not.
