Can I use a generator whose wattage exceeds the wattage on the Reliance Pro/Tran? transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
This is acceptable for peak wattage but not recommended for running wattage. Pulling more than the rated wattage through the Reliance Pro/Tran? transfer switch could burn out the neutral wire, overheat the main wiring in the transfer switch and cause a fire. To insure proper safety precautions, a suitable double pole breaker should be installed between the generator and the transfer switch when the running wattage of the generator exceeds the rating of the transfer switch.

Can I use a generator whose wattage exceeds the wattage on the Transfer Switch?

Gentran Corporation: Generator Transfer switches for home & ...
NO. While it might be possible to connect a larger generator to the transfer switch, this is an unsafe and dangerous practice. Supplying more than the rated wattage through the transfer switch could damage the wattmeters, damage the neutral wire, and could overheat the main wiring in the transfer switch, which could cause a fire.

Which Power Inlet Box can I use with each Reliance Pro/Tran? transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
A four-wire, twist lock connector is needed. Reliance manufactures suitable Power Cords with a male connector on one end and a female connector on the other end. The four wires consist of two 120-volt "hot" lines, one neutral and one ground. The main difference is that the Pro/Tran? Series can easily be either hard-wired to a remote power inlet box or cord-connected to the generator, whereas the Gen/Switch??? was designed to be only cord connected.

Can I use a Reliance Pro/Tran? transfer switch on any 20-amp circuit in my house?

Reliance Controls Corporation | Frequently Asked Questions
Yes. The switches and wires in each transfer switch are rated for 20 amps. However, in the generator mode, each circuit is limited to the amperage of the circuit breakers in the Reliance Pro/Tran? transfer switch. Some of these breakers are 15 amps and some are 20 amps. The circuits with 15 amp transfer switch breakers can be connected to either 15 or 20 amp circuits in the main panel. The circuits with the 20 amp transfer switch breakers must be connected to 20 amp circuits in the main panel.

How long does it take to connect a Reliance Pro/Tran? transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
About an hour by a qualified electrician familiar with residential wiring electrical codes. If installed with a power inlet box, the installation could take slightly longer. Since each unit is pre-wired, the installer simply needs to determine which circuits will be needed during an outage, wire each set of wires in the transfer switch to those circuits, install the neutral and the ground, and test the installation under load.

Can I hardwire my Reliance Pro/Tran? transfer switch instead of using a power cord?

Reliance Controls Corporation | Frequently Asked Questions
Yes. Even the cord-connected models can be hardwired. Use the cover plate supplied with every unit to cover the power inlet opening.

Are Reliance Pro/Tran? transfer switches automatic?

Reliance Controls Corporation | Frequently Asked Questions
They are manual transfer switches designed for residential or light commercial use with a 5000-12,500 watt standby generator.

Are Reliance Pro/Tran? transfer switches pre-wired?

Reliance Controls Corporation | Frequently Asked Questions
Each Reliance Pro/Tran? manual transfer switch comes completely pre-wired with a Red and Black wire for each circuit, plus a white neutral and a green ground wire. Reliance Panel/Link? models are generally not pre-wired, the exception being the TRC Series suffix "P" which come with 12 pre-wired circuits including the branch circuit breakers. The Reliance Pro/Tran? "Q" Series manual transfer switches are specifically designed to handle high wattage appliances.

What is the maximum load on each side of the Pro/Tran? transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
The wattmeters on each Reliance Pro/Tran? transfer switch allow you to balance the load on each of the incoming 120 volt lines in order to gauge how much generator capacity is being used and to maximize generator performance. No meters are needed for balancing on the 4-circuit Models 15114A & 30114A since they have only one leg. Meters are not standard on the Pro/Tran??? Models 31406B, 31410B, 51406B and 51410B. They can be added at any time by installing the optional Watt Meter Panel.

Why does the whole generator GFCI trip on my Honda generator when I use it with my transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
Certain Honda Industrial/Commercial generators have the neutral bonded to ground to pass OSHA inspection on job sites. Since home or building main breaker boxes also have neutral bonded to ground, two parallel paths back to the generator are created, one using the neutral wire and one using the ground wire. The neutral current now flows through both conductors.

What is a generator transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
A transfer switch isolates those circuits using generator power during an outage from the utility power. This eliminates the risk of back feeding the electric utility, which can cause injuries to utility workers and property damage.

What size of a transfer switch do I need for my generator?

Gentran Corporation: Generator Transfer switches for home & ...
First, the transfer switch you select should match the maximum continuous wattage rating of your generator. For example, if you have a 5000-watt generator, you should select a transfer switch rated at 5000 watts, such as Model 200660. You may also select a transfer switch that has a higher rating than your generator. (Ex: a 5000-watt generator with a 7500-watt transfer switch is OK.) But NEVER install a transfer switch with a lower rating than your generator.

Can I use my existing Reliance Netconnect when I switch from one model to another?

Lambert Cables & Communications - India
It depends upon the make and model. Some manufacturers use the same modem across all models (Example: Samsung) while some have model specific modems. It is recommended that when you switch models you reinstall the Reliance Netconnect software.

How many double-pole 240 volt circuits are provided on each Reliance Load-Side? transfer switch?

Reliance Controls Corporation | Frequently Asked Questions
The 6-circuit models can be configured for one (1) 20 amp double-pole circuit for use on one 240-volt circuit, and are provided with one (1) handle tie. The 8-circuit models can be configured for up to one (1) 20 amp and three (3) 15 amp double-pole breakers, and one (1) handle tie is provided.

What happens when the Utility Power is restored while I'm using my generator and transfer switch?

Gentran Corporation: Generator Transfer switches for home & ...
When your utility power is restored, lights and appliances in your home not connected to generator power will turn on; alerting you that utility power has been restored. Because Gen/Tran PowerStay? Transfer Switches have interlocking main breakers, the utility power and generator power are never powering those circuits using generator power at the same time. There is no danger of back feeding the utility power. No.

What wattage can I use?

APS :: Frequently asked questions regarding CFLs
CFL packaging explains the incandescent wattage to the CFL equivalent. An example: A 14 W CFL is equivalent to a 60 W incandescent bulb. A simple rule of thumb is incandescent wattage divided by 4 equals the proper CFL size. Always follow the fixture guideline for sizing of the bulb.

NOTE: AFFECTED MODELS ONLY INCLUDE: HONDA Models EB3500XK1, EB5000XK1, EB6500SX, EB12DAG, Arctic Cat Model 1999 AC7500GD2EB and some models from Briggs and Stratton. The Honda EB (Industrial/Commercial) series generators listed above have their neutral wire bonded to the ground wire to pass OSHA inspection on job sites. Since home and building main load centers also have the neutral bonded to ground, a loop is created, comprised of the neutral wire and the ground wire.

How does the switchable wattage switch work?

Reverend FAQ
The Hellhound switch lifts the cathode from ground, limiting the conductivity of the output tubes. It is based on a variable wattage control patented by Dennis Kager (see above). The switch on the current line of amps limits the drive signal to the output stage. This is a new circuit design also by Kager.

How do I know what wattage to use in my fixture?

Frequently Asked Questions - Lighting Supply Company
Whenever replacing a lamp you must check the fixture for wattage and voltage requirements. With an incandescent light fixture wattage becomes a preference depending on how much light is needed. With fluorescent or high intensity fixtures the wattage is specific to the ballast built in the fixture. CAUTION: Using the wrong lamp in a fixture could cause the bulb to burnout early and may create a fire or safety hazard.
