Double Male Electrical Plug

Every year when people start decorating we get MANY requests for an electrical plug with male prongs on each end.  We don’t have them.  To my knowledge they don’t exist. 

Christmas lights have a male plug on one end and a female plug on the other.  They are made this way so that you can connect several strings together without running multiple extension cords.  You only run into problems if  you string the lights starting with the wrong end. The female plug is where you intended to plug the lights in.  To make them work you need an adapter with 2 male plugs.  The problem is that if you plugged the 2 female ends together there is going to be a totally uninsulated male end somewhere that is live.  An extreme shock and fire hazard.  The solution is to either run an extension cord to the male plug at the end of the string or take the lights down and redo them starting with the male plug end.

    One would have to be crazy to want a male to male adapter or extension cord. Unsafe is an understatement. Another problem with this type arrangement is often found when people want to connect generators using a similar process of feeding power to their house outlets by “rigging” up a male to male plug. This presents a fire and shock hazzard not only to persons at your house but to power company employees working on power lines that may be having power fed back into them from your “rigged” connection from your generator. So better be safe than sorry for all concerned. DONT connect anything with a male to male plug.

    They do exist. Search Dual male electrical plug and you will find a variety from plugs to extension cords. What causes such a hazard that you recommend not to use them. Thanks for the info.

      I have been an electrician since 1952, journeyman, licensed contractor, master electrician,and I have never seen a double male plug adapter. I only get requests for them at Christmas when a homeowner puts his light strings up backwards.

      Plenty of (non)electricians, (homeowners,gardners who think they know electrical)mfgr their own, by using a piece of zip cord to wire two male, two prong plugs togethwer.

      A good way to elctrocute, friends and family during the holidays.

    Nathan: A “Dual Male Plug” is totally different than a “double male plug”.

    I have a Honda E3000i pwr generator, and in order to use the RV 30 amp outlet, you need a male twist locking plug. Almost all RV 30 amp connection use a standard RV 30 amp male plug. In order to be able to use the 30 amp side of this generator, I have to plug a RV 30 amp male into an adapter with a 30 amp twist lock plug.
    Occassionally, I need to extend the lenght of electrical hookup by using a spare 25ft 30 amp cable which has a female twist lock 30 amp connector on one end, and on the other end: the standard RV 30 amp male plug. It’s quite functional, logical, praticial solution, and works for my need. I’m sure, on numerous occassion, others have a similar requirement. I would just like to be able to buy one so as to keep the plug/combo water tight from the weather.

    Well you might want to go thru a hurricane and tell me exactly how to connect a generator ( portable cause some of us can’t afford a wired hole house system) to your house wiring and have it work!
    Taking a double male allows one end in generator and the other into a house circuit like a kitchen where the frig will work.
    That is the best reason for double male.

      Yeah, double male works great on a generator until you forget the main to the house is still on and you fry the lineman that’s fixing the line. If you can afford the generator, you should be able to afford having it wired up right.

    Here’s how to go through a hurricane and connect a portable generator to your house.
    1. (The best way) Have a professional electrician wire a transfer switch into your home breaker box/fuse box. You can tell him/her what the capacity of your generator is, and what you would like to be able to run off of it. He can tell you what is capable based on the size of your generator and then install a receptacle on the outside of your home that you can then plug your generator into when the power is out at your home.
    2. (The cheaper, more temporary way) Run extension cords from the generator into your house through windows/doors to the appliances that you’d like to run.

    If you must have a double male cord for emergency use, here’s how to make one. You must do this while the house still has power (that is, before a hurricane or whatever.) Don’t wait until you lose power to do this…. Be Prepared!

    Here’s how to make a male to male extension cord:
    Step 1: Move to Europe, where the 220-240v line voltage is absolutely fatal, instead of the only mostly fatal 120v lines here.

    Step 2: Buy a European extension cord (male to female), a male European plug, and some wire cutter/strippers. Pro tip: Make separate trips, one for the cord, and one for the plug/tool. We don’t want some do-gooder seeing what you have and interfering with our plans.

    Step 3: Cut female end off of extension cord, and install male end in its place, making sure to follow the instructions that came with the male end exactly, so that hot goes to hot, neutral to neutral, and ground to ground. You probably don’t have to worry about properly strain-relieving the cable, or even installing the back of the connector.

    Step 4: Make sure one end of your new male to male cable is free from touching anything, and then plug the other end into a good working outlet that you know has power. (Test first by plugging in a light or something.)

    Step 5: Once one end is firmly seated in the working outlet, carefully grab the other end BY THE CABLE, not the connector.

    Step 6: Being careful to touch only the cable with your hands, place the free male connector in your mouth and bite down hard on the prongs sticking out of the male connector.

    Step 7: Thank yourself for doing your part to tidy up the gene pool.
