Power Spy™ #34 30A 240v OUTDOOR power monitor for Generators – L14-30 plug to L14-30 outlet on 1' tails with twin kWh meters
Outdoor Rated High Quality Made In the USA Polycarbonate Enclosure
The Power Spy™ #34 30A 240v Outdoor allows you to monitor your L14-30 outlet's energy usage from your portable generator or any thing else. Now you can see exactly how much your home or anything else equipped with an L14-30 plug is using for power. The beautiful four color meters tell you instantly what your individual line voltage is, your amperage draw is, your wattage draw is, and it even accumulates kilowatt-hours (kWh's). Each meter runs at 120 volts and reads one Phase. This unit was specifically designed as a great solution to monitor the energy usage from portable generators utilized outdoors. You can multiply the kilowatt-hours by your local electrical rate to see how many dollars and cents it costs to run your particular device. We pay approximately $0.14 per kWh here in Las Vegas. The totals are accumulated until you press the recessed reset buttons underneath the removable polycarbonate window. The total is even held during power outages. This model's window has a heavy weather seal and is equipped with stainless steel tamper resistant screws threaded into brass inserts for easy repeat removal. Built from a high quality Polycarbonate case for maximum strength and durability. This unit is built with quality name brand molded L14-30 connectors for weather resistance. Great for home backup, Fair Grounds, Commercial buildings, RV Parks, Boat Marinas, anywhere you need to keep track of power usage! The Power Input cord is offered in several lengths, the Power Output cord is on a 1' tail. Features a compact body at only 6.4 x 4.4 x 4.3 inches, the smallest Power Spy™ we offer. Includes top and bottom rear mounting flanges with both corner holes and center keyhole slots for versatile mounting. I can certainly customize the lengths for you, just email me and I am happy to give you a quote.
Warranty Note: It is imperative to keep the plug blades of the Power Spy and anything plugged into the Power Spy clean and free of corrosion. The metallic parts of the male and female connectors are made to resist corrosion. A marine environment is one of the harshest outdoor environments. In a salt-water environment, life of the product can be increased by periodically cleaning the exposed parts with fresh water, fully drying, and apply Gardner Bender® Ox-Gard on at least a monthly basis. In the case of Salt Water Immersion; disconnect from power source. Rinse plug end or connector end thoroughly in fresh water, shake, or blow out excess water and allow to fully dry. Spray with Gardner Bender® Ox-Gard. Neglecting to follow these imperative care steps will result in connector corrosion leading to overheating and eventual failure not covered by the BSA Electronics warranty.
Need some help identifying your wall outlet? We can help! Below is a description of the more common NEMA outlets and their numbers as well as some handy NEMA plug charts. You can also email us a pic of your plugs and outlets you need help identifying and we would be happy to help.
Here are the more common NEMA outlets:
- 5-15 standard 15A 120 volt household outlet, the most common you see everywhere.
- 5-20 standard 20A 120 volt household outlet, required by code in bathroom and behind your refrigerator.
- 6-15 standard 15A 240 volt household outlet, found in homes and motels for running in-wall Air Conditioners, it’s the smaller brother to the NEMA 6-20 outlet. The 5-20 is not as common as a 6-20 outlet with it’s “T” shaped slot as it will accept both 6-20 and 6-15 plugs.
- 6-20 standard 20A 240 volt household outlet, found in homes and motels for running in-wall Air Conditioners, also found occasionally in residential garages.
- 6-30 standard 30A 240 volt 3-prong outlet, found in shops and garages used for medium size welders.
- 6-50 standard 50A 240 volt 3-prong outlet, found in shops and garages used for large welders.
- 10-30 standard 30A 240 volt 3-prong Dryer outlet found in homes build before 1996, replaced by 14-30 in 1996.
- 14-30 standard 30A 240 volt 4-prong Dryer outlet found in homes build in 1996 and newer
- 14-50 standard 50A 240 volt 4-prong Range (electric stove top) outlet, also called RV-50 at the RV parks. By far the best universal connector to have for an EVSE. This is the one the Tesla guys install in their garages.
- 10-50 OLD 50A 240 volt 3-prong Range (electric stove top) outlet, also found in old shops used for large welders, replaced by 14-50
- TT-30 (Travel Trailer 30amp) 30A 120 volt 3-prong outlet, the older style found in RV parks, not used in residential homes.
- L6-30 (locking 240 volt 30amp) Twist-Lock 30A 240 volt outlet, my personal favorite locking connector, easy to find in stores, works great for adding adapters to portables EVSE’s equipped with a L6-30 plug. Commonly used for CPU server racks and PDU’s
220/240 volt outlets are commonly installed with the ground pin towards the ceiling for safety. 110/120 volt outlets can be found mounted in all directions. Be sure to carefully look at your outlet and the chart, it's easy to mistake one outlet for another if your outlet has it's ground pin facing the floor instead of the ceiling or Vice Versa compared to the chart.
In the full NEMA number you will see a capital R or P. The R stands for Receptacle (outlet) and the P stands for Plug, we commonly truncate this to just the numbers and add the word receptacle (or outlet) at the end. For example 14-50R becomes 14-50 receptacle or 14-50 outlet.
