cargo trailer is grounded, but only 3 wires going to 4 prong male generator plug. Need to convert 4 prong to 30 amp rv regular service, but only 1 leg works.
The four prong plug is usually for 220 volts. Two wires are power, one is common and one is for ground. You may find that one or the other power wire to ground ( or common) will read 120 volts. Check what type of generator you have, power etcetera

power generator how to connect power generator to travel trailer batteries with auto ON capabilities?
I have a travel trailer that has two 12v (car size) batteries. I am buying a power generator (Gas) and would like the power generator to automatically start when ever power is needed to charge the batteries, or powering say Air conditioning unit. (the Power generator does have an electrical start.
you should be able to get what you are looking for where you bought your genny as far as starting say the a/c it is a on demand switch and you will have to put a elec starter on to do this (also where you bought the genny)

How do I plug the output of an AC generator into a power meter?
Hi! I have a solar powered AC generator (5hp AC motor spun by a stirling engine), and I want to put the outputted energy into the power grid. However, I don't know how to connect it so that the engine will spin the motor (producing current) rather than the motor spinning the engine (sucking current). Any (good) ideas?
Thanks in advance!
You need to talk with your power company before you attempt to connect anything. There are serious safety concerns with supplying power back to the grid and a special meter is required if you want to get paid for it in most locations. When I say serious I mean you can kill somebody besides yourself.
Vent Base How do you tell the difference between an 2007 Infiniti G35 Sedan Journey and Base model?
so like my title says, how do you tell if the 2007 g35 sedan is a base model or it is a journey? I believe journey has rear air conditioning vents. but are there any other differences to tell if it is a base or journey? Thanks
A Sport Package is available on the Journey. Powered by a 3.5-liter V6 engine making 306 horsepower the Base and Journey receive a five-speed automatic transmission with manual mode, while the Sport 6MT is only available with a six-speed manual transmission
Lighting any workplace costs money, yet businesses lose profits every day by paying to operate lights in unoccupied rooms. A better solution is to install automatic lighting controls—called occupancy sensors—that can switch lights on and off based on occupancy, time of day, and the room's ambient light level.
Are occupancy sensors a smart solution for your business? Read on to learn more about these energy-saving devices and how they may be able to help your business save energy and money.
WHY INSTALL OCCUPANCY SENSOR CONTROLS?
Lighting occupancy sensors save energy and money by detecting activity in work areas and automatically turning lights on when people enter a room and off when people have left. Used properly, occupancy sensors can be a cost-effective way to reduce the operating time of lighting systems, resulting in outstanding energy savings.
One type of occupancy sensor is called a vacancy sensor. Vacancy sensors must be manually turned on by an occupant entering a space, but will automatically turn the lights off if no activity is sensed after a set period of time.
Vacancy sensors work best in smaller enclosed areas where occupants entering a room can easily access the sensor.
Occupancy sensors are most effective in spaces that are frequently unoccupied, including offices, warehouses, storerooms, restrooms, loading docks, corridors, stairwells, office lounges and conference rooms. Open-plan office spaces, where activity level may be high thoughout the workday, may not be good candidates for occupancy sensors that control the general lighting, but may be a good place to consider sensors that control plug-in office equipment and lighting at workstations.
HOW OCCUPANCY SENSORS WORK
Occupancy sensors typically consist of a motion detector, electronic control, controllable switch (relay) and power supply. Most units detect motion by sensing heat (infrared radiation), shifts in the frequency of reflected ultrasonic waves, or a combination of the two. When the sensor detects motion, the electronic control sends a signal to the relay, which opens or closes the power circuit, turning the lights on or off.
TYPES OF TECHNOLOGIES
Passive Infrared (PIR) Occupancy Sensors Infrared sensors detect the difference in heat emitted by humans in motion from heat emitted by the background space. While they are resistant to false triggering, they require a direct line of sight to sense motion.
The sensitivity of PIR sensors to small movements decreases at distances greater than 15 feet. As a result, these sensors are best suited for smaller, enclosed spaces where the sensor has a view of the activity in the room and warehouse aisles. The sensor's field of view can be adjusted and should not be directed toward an open door where it may pick up people who are passing the doorway, but not entering the room. Ultrasonic Occupancy Sensors Ultrasonic sensors emit a high-frequency signal that is undetectable by humans and animals. This signal bounces off objects, surfaces and people in a space. It then returns to the sensor, which interprets change in the frequency as motion.
While these sensors do not require a line of sight and can sense movement around corners and objects, they may be prone to false triggering if placed too close to an HVAC vent. Ultrasonic sensors are highly sensitive to small movements up to 25 feet. They typically offer a larger coverage area than
PIR sensors, but should not be mounted in high ceiling applications (over 14 feet).
Dual-Technology Sensors
Dual-technology sensors employ both PIR and ultrasonic technologies for maximum coverage and reliability with fewer false triggers. Because these sensors activate lights only when both technologies detect movement, and because either of the two technologies is enough to hold the lights on, these sensors significantly reduce the possibility of false on and off triggers.
High-Bay Sensors
One of the most cost effective applications for occupancy sensors is in warehouse aisles because these areas are not occupied on a constant basis. For warehouses with highintensity discharge (HID) light sources, lighting can be switched to a lower level, but it can't be turned completely off. HID light sources need time to cool down and warm back up to full light output. This process takes too long and is not practical for those who need to perform tasks in the space.
"High/low" occupancy controls can switch lighting from full light output to approximately one-third light output (which uses about half the power) when the area is unoccupied.
When the sensor detects activity, the light level and power are restored to full almost immediately.
For even greater savings and instant on/off capability, consider replacing HID fixtures with high-bay fluorescent fixtures. High-bay fluorescent fixtures use much less energy than HID, and can be switched on and off as occupancy and vacancy is detected in a space. High-bay sensors can be individually fixture mounted, or a single sensor can control a full aisle of light fixtures. Placement and delay settings are important to prevent false triggering by detection of activity in the main walkway that does not move into the actual controlled aisle. Placement is also important to make sure that the sensor can "see" any activity anywhere in the aisle being controlled to prevent the occupant from being left in the dark.
WILL OCCUPANCY SENSORS WORK FOR YOU?
While occupancy sensors may reduce lighting by 50 percent or more in some circumstances, the savings could be much smaller, so it's important to consider a wide range of issues before installing a sensor in a particular location.
To determine how much benefit you will gain in a given application, monitor lighting use patterns and occupancy patterns simultaneously. From this, you can calculate the number of hours your business will save in lamp operation, and then determine your energy savings.
You can establish lighting use patterns in a number of ways—by observing and recording when the lights in different parts of your facility are left on, including after hours; by talking with custodial staff and security personnel; and by reviewing the settings on lighting timers. You can also use a device called a datalogger, which counts lighting hours and logs lighting times and durations. A lighting professional can help you with this process.
Those do it yourself renewable energy guides had me curious. Is it really possible to learn how to make a solar panel, from parts you can purchase online, or at your local home center? I have to admit that like you probably are, I was very skeptical about all of this.
What I had been interested in doing for some time was create a source of power for my weekend cabin in Montana. I didn’t need a lot of power, just enough to run some lights and a cell phone charger. So I did some research, and settled on a downloadable guide called GreenDIYEnergy.
I spent the first day just going through all the material, and there is quite a bit of it. There is a comprehensive guide for learning how to make a solar panel, and another guide showing you how to make a wind turbine. One thing I really did like about the guide was the abundance of videos. And not some poor quality videos that look like they were shot from a cell phone camera, but good quality videos complete with narration.
I was able to get some cheap solar cells from Ebay. The rest of it, such as the framework for the solar panels, I made myself. The whole thing went together very smoothly and I tested it to confirm it was producing power. I really felt a great sense of pride knowing that I actually created something myself that can produce electricity.
Today I have a nice little 3 panel solar setup at my cabin. I installed a bank of batteries and an inverter to turn the DC power into usable AC power. Overall I felt that the guide was very easy to follow. The directions covered every detail of wiring it together and hooking it up. And when I did have a question, it was answered in a timely manner.
I wanted to write this review because one thing I noticed is that about 99.9% of the so-called reviews of this product on the internet were pure garbage. It quickly became apparent to me that none of those “reviewers” ever looked at the GreenDIYenergy guide, much less made anything with it.
To summarize, I think this is a worthwhile investment if you want to learn how to make a solar panel for your home, place of business or like me, in a weekend cabin or RV.
