The risk in connecting the wrong wire first is that you could create a short in the system if you put the wrong wire on before the right wire. RV Battery Hook up Positive or Negative First? Not every electrical device will follow the rules or the traditional house wiring setup. if that doesn’t confuse you already or make you scratch your head then those odd situations where devices use different colored wiring will. The DC side will have red as the positive and black as the negative.

At least on a 2 wire system.īut as mentioned earlier, this color code system only works for the AC side of the RV electrical system. Black is the positive or hot wire and white is the negative or ground wire. RV Battery Hook up Black And Whiteīy now you should know that this color code system is the standard color code system for traditional house electrical systems. It would be wise to study the different electrical systems that are on your RV because that knowledge will save you a lot of trouble.

If you do make this assumption, then you are only setting your system up to blow a fuse. You cannot assume that the colors on the wires go to the same terminals on different systems. it can get confusing if you have experience in different electrical systems. The red would be the positive or hot wire on the DC side of the system and is replaced by black when the electrician is wiring the AC side. Black is used for the negative on the AC side of the system.

The white-colored wire is supposed to be the negative or ground wire on the DC electrical side of the system. For further help, you may want to look up the following guidelines- RVIA Adopted Standards12-Volt Electrical Requirements as specified by ANSI/RVIA 12V Low Voltage System Standard. The DC side has been reported to use the standard car configuration and use a red wire for the hot or positive side of the system.īut then, there are those manufacturers, who for some reason, went to all white wires and used different colored stripes to identify what the wire is supposed to be used for. However, that only works for the AC side of the electrical system. They did not want to confuse the electricians when they had to replace or repair any wiring. It has been suggested that the RV manufacturers decided to go with black as the hot wire and white as the negative wire because they followed the traditional house wiring system. Here is a link with those diagrams and explanations so you can get the right picture without a third party getting in the way and messing up those explanations. There are several diagrams that will be helpful to you but we cannot lace all of them here at this time.Įach one would need some explaining if you are going to DIY your wiring. The diagrams can be very confusing when you are a novice or unsure of how electrical systems work. If you are not comfortable with working with electricity or wiring, then you should turn the task over to a qualified electrician who knows his stuff. The problem comes with the wiring method because it is easy to do it wrong and mess up your entire system. The parallel method helps bring the power you need to all your devices without draining the batteries too quickly. Generally, your system may have 2 batteries connected in a parallel system. Sometimes you may have a green wire involved and when you are not sure, it is best to let a qualified electrician handle any wiring problems you may have. If you connect this wire wrong, you can damage the inverter and the wiring system.

When this happens the red is not the hot wire but the lead from the inverter to monitor if there is a charge going to your battery. You may get a white, black, and a red wire leading to your battery. However, you may have more than one device connecting to your battery and the red color may not be the positive or hot wire. This is the simplest picture you can have. The standard picture will have your battery with a white wire connected to the negative terminal and a red or black wire connected to the positive terminal. As it stands at the moment, the RV makers will try to follow standard traditional house wiring rules when wiring 120-volt wires but when it comes to the battery system, anything seems to go. If you face that situation then you have to do some research as to which wire goes to which terminal and the frame. That is if the RV manufacturer did not throw you a curveball and use all white wires with some color stripes. The white wire is the ground or negative connection and needs to go to the negative terminal and the RV’s frame. For an RV system, the black wire is the hot wire and needs to be hooked to the positive terminal. However, when you are working on a battery for your RV, that is not going to be the case. Generally, you hook red to positive and black to negative.
