With no colour coded insulation, knowing which wire is hot

I have to replace a 3-pronged plug on a heater. I stripped the 3 wires in the cord. Both the 2 outer wires have no colour-coded insulation to tell me which is hot or neutral. One does have printing on it. Would that be the hot wire?

Take your old cord out. If you notice there is one side that is a little bigger than the other. Take a meter and measure the continuity from the larger side to the wire end and thats how you can tell which is which. Do the same on your new cord and that will tell you which one to put where. Like this..... ------>l l<----

Plug, prongs & a portion of the cord (for about 2 in. from the plug) get very hot when in use. Prongs are actually too hot to the touch. Have replaced the plug once, still the same problem. Any info...

This often times is that the plug (outlet) is not heavy enough to support the heater. Go to your hardware store and buy you a twenty amp replacement outlet, normal outlets are rated ten to fifteen amps. This should take care of your problem, also in doing this check the wire to the outlet and make sure it is not burnt.

Fan goes to slow speed when power cord is bent near unit.

This is a sign that the wire is possibly broken inside the insulation and would cause an amperage drop causing the fan to run slow. I suggest that you replace the cord with a cord of the same wire size and new plug. Myself I like safety factors so if the cord says it is #14awg go to #12awg and use a twenty amp rated plug be safe not sorry.

I have one of the older models of delonghi but the plug got burned off due to attaching and improper extension cord. Is there a possiblity for the cord to be replaced

I don't know how much trouble it is to access the heater end of the cord but if you can see how to do it, it would be a good time to replace the entire cord & plug. Any of the home improvement stores (if in the US) will have the right materials and you will have the chance to lengthen the cable to eliminate any extension cord. Make it 20' if you choose, the wiring will handle it.
Ask or look for a 3-conductor flexible heavy appliance-type cable with at least a 15 amp rating. This may be marked as 2/12 and will have a third wire for safety ground, generally colored green. The other two will be one black and one white insulated conductor. When properly wired, the white is neutral, the black is 'hot.' The plug will be fairly large and have screw terminals for the three wires. This type of replacement plug will handle any 120 V household appliance. The actual blade contacts that go into the receptacle may have one wide, one narrower, and one round pin for the standard outlet. The wide blade inside terminal for the wire is intended for the white insulated wire, the narrow for the black and the ground (green or green/yellow) insulated wire goes to the round ground pin's screw terminal. These plugs are equipped with a substantial strain relief under which the entire cable diameter is clamped.
Inside the heater's attachment area, there should be currently wires attached that correspond to those in the new cord but if not, they may be marked as in Europe (the brand is Italian) and that may have changed since I left there years ago. If you find the following colors, substitute the paired color for US use:
- Brown = US black = Hot - Blue = US white = Neutral - Green or green/yellow = US green or green/yellow = Ground
If you find anything else, let a professional connect the new line for your own safety.

Power cord overheating at outlet - melted cord a bit - very scary will not use anymore - my outlet looks a little brown now - Delonghi 9707 electric heater

Hi, what causes this could be a couple of different things. Yes, do not use this outlet until the problem is solved. Normally this is caused by your heater drawing more amperage then it was intended to do, due to a problem in the heater . Not knowing the age of your home, the electrical wiring through out may be the old aluminum wiring that has stopped being used due to the problem of this type of wiring heating up at outlets causing them to burn the insulation off of the wiring, burning out the receptacles, and in many cases in the past, burning down the home, not to to scare you. I will offer you some solutions to find out if your home is wired with aluminum wiring. Don't be afraid to do this for me. You need to find the breaker that shuts the power down to that outlet and area of the house. If you are not afraid to plug something into it for a few minutes and have a helper turn off breakers until you know it is dead. Once you have done this, take a regular or phillips driver and remove the 1 screw to take off the plate cover. Now, remove the 2 screws at the top and bottom of the outlet. This will take it loose from the electrical juntion box, so you can get a look at the wiring and damage to this. Normally, you will see any where from 3 up to six wires depending on if its what we call the start of the run, middle of the run, and so on. Wire colors will be black for hot and white for neutral. You will know if the wiring is copper or aluminum. If you think you are up for this, you can change this yourself. A new outlet is about $1.19. 1st, buy a couple so you will have a spare. The newer ones have screws on the side, and on the back have quick connects to strip the insulation back and just plug and push into a small hole that locks the wires. Facing the plug, black should be on the left side and white on the right. Another way to tell on the new plug is the color of the screws that hold the wires in place. Look at it and on one side the screws will be brass in color which is for the hot black wires. The other will be silver in color for neutral. If you find that the wiring is aluminum, there is nothing you can do but make sure all wiring connections are always tight! If you have to go through the complete home a little at a time to check all outlets only if they are aluminum, its worth the time! Do this once every couple of years or so and check and tighten, not so with copper wire. If copper, just check the one outlet. You can pick up a inexpensive pair of wire strippers and if the wire is aluminum, buy a small tube of nolox which is a gray paste they use on aluminum wiring to help keep it from oxidizing. Has different names, but you will find what you need in the same isle at home depot to do the job. Just cut off any brittle or hard wire and strip a 1/4 inch off the ends, either wrap around the screws on the side cw, not ccw, or use the quick connects in the back. When you are getting these items, pick up a new cord for your heater. Very easy to replace. Just follow where the cord goes into the heater until you find where the ends terminate and remove the old and install the new. You will have to have a few connectors and remove a cover on the heater, but really it is very simple. Just remember this, if the wiring is copper just get a new outlet and replace that and the cord. I believe this all started with that one outlet having loose wiring. If you don't feel like you can handle this, you still need to find out what kind of wiring you have so you are up on the dangers and consult a electric repairmen. I sincerely hope I have given you some direction to follow on this, and hope you will take on these minor repairs. Please be kind as I know you will, when rating this thread.
A/C, Heating, & electrical Contractor
PS, just to say there will be a ground wire normally bare that will connect to a screw on the corner of the new plug, depending on the age of your home also. If no ground wire, leave it blank :))

I do not know how to wire the plug box from my

Hi, I am not completely Sure what you mean, but will explain the connections. First, from your breaker box if you are trying to wire a 3-pole cord and plug to the breaker, you will be dealing with 3 wires, more then likely, Red -Hot, black-Hot, and white Neutral. If you have a 30amp 2-pole breaker, make sure it is off and red goes to one leg of the breaker, black to the other, and white to the ground or neutral buss bar. Each leg is 120 volts,=240. I am trying to cover all of the bases here for you. The plug it self has 2 brass colored connections for the 2 hot and 1- silver for the white. Maybe a ground, but doubtful. I hope this has given you some direction to go by. If you need more help or not sure, please leave a message for me so we can get this right for you. Let me know one way or another. Good Luck,

I need to wire a new pulg onto my heater

normally you will have four wires in the cord: a red, a black, awhite and a green. The red and black are the hot or power wires the white is the neutral and the green is ground. Purchase a plug that matches your outlet pattern (that will plug in). Shut off the circuit breaker that feeds the outlet and remove the cover. strip the insulation back on the cord, determine which wire goes to which lug or terminal and connect the wires to the plug. reassemble the outlet and the plug, turn on the circuit and test. If all of this is greek to you, call a local electrician and pay them the $50 to $80 to put the plug on for you, its safer that way.

Electric Hydronic Baseboard Heater Under Electrical Recepticle

I believe you interpretation of the code is a bit skewed in that the fundamental concern is to not route power cords over a heat source which might cause the insulation on that wire to exceed its rated operating temp and fail. The heaters themselves have shrowds over them so there are no exposed surfaces hot enough to melt wire insulation and when you think about it ..2000 watts disipated over a long baseboard section is not that hot. If I were you, I would go ahead and install them and not worry about the warning.. The warning also removes any liability from the heater manufacturer in the event something happens.. Common sense would dictate that you wouldn't intentionally drape power cords all over the heaters... Just use common sense and not worry about it..

Which of the outside wires is the hot

one of the conductors has a rib impressed into the insulation - this is the "identified" conductor and goes on the nickel colored screw of the replacement plug. the other is the "black" or hot and goes to the brass colored screw.
