How do you connect a 240 volt heater that has one red wire and one black wire?

1. If the heater itself has Green, Black and White wires coming out of it, those wires are likely to be: Green for Ground, Black for Hot and White for Neutral. (As in the wiring codes for the US or Canada or countries which use similar wiring codes.)
2. When the question goes on to say "Terminals are Brown, Blue and Black", that seems to be in conflict with the information stated above in Line 1. Exactly which terminals are you describing? Are they on a plug on the cable already coming out of the heater? If it is a US-style plug then it might be for use on a 240 Volts outlet, in which case the pins on the plug would possibly have a Brown terminal for the Red "hot" , a Black Terminal for the Black "hot" and a Blue terminal for the Neutral?
3. Alternatively, maybe the questioner is in the UK, and the terminals being described are actually inside a UK-style standard 3-pin power plug, which could have a Brown terminal for Load, a Blue terminal for Neutral and (possibly) a Black Terminal for Earth (= Ground).
4. If the terminals being described in the question are not inside a plug, where exactly are they? Are they in a wall box intended for a hard-wired connection to a water heater?
5. If this is actually an appliance designed for use on 60 Hz supplies such as in in the US or Canada, which it sounds as though it may be from the colors of the wires given in Line 2 above, then you need to check very carefully if it was designed to be used on a US-style 120 Volts outlet, not 240 Volts. THERE SHOULD BE A RATING PLATE ON THE HEATER WHICH TELLS YOU THE VOLTAGE IT WAS DESIGNED TO USE. IT SHOULD ALSO STATE THE POWER TAKEN BY THE APPLIANCE. For domestic or office use it will probably be 3 KiloWatts or less.
6. If the rating plate says the heater was intended for use on a US-style 120 Volt supply, do not try to use it on a 240 Volts supply! (If you do, a fuse will blow and/or a breaker will trip!)
7. If the rating plate says the heater was intended for use on a US-style 240 Volt supply, then, if it is to be used on a UK 240 Volts supply using a UK standard power plug, wire it like this: Black wire to the Brown Terminal in the plug (labelled as Load or Live), White wire to the Blue terminal in the plug (labelled as Neutral), Green wire to the Earth terminal in the plug.
Black goes to brown, white goes to blue, and of course green would be your ground.
Always be sure to switch off the main power switch and breakers at the main panel before you attempt to do any work on any mains power circuit.

∙ 14y agoTo energize a 240 volt heater that has one red wire and one black wire you will need a voltage supplied from a two pole breaker. To tell the size of the breaker and the wire size to feed the heater the wattage has to be known.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.
Does the ground wire from a 240 volt tankless water heater connect to the common wire?
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
Can you connect a 3 wire 120 Volt with ground to a 2 wire House wire has black and white and ground Appliance has black red white and ground?
To answer this question fully the type of appliance has to be stated and its voltage.
How many 240 volt electric baseboard heaters can you connect to a number 10 wire?
Depends on the Amperage of each baseboard heater (how many watts each one draws).
Negative 12 volt wire?
black
Where does the red wire in a baseboard heater connect to the black or white wire in the wall?
In the heater you will have two wires. You should then have 2 supply wires from the panel, and 2 wires from the thermostat. The neutral (white) supply wire should go to one of the wires on the heater. The hot (black) supply wire should connect to one wire from the thermostat. The other wire from the thermostat will connect to the other wire from the heater.

What wire do I connect the 277 VAC wire to?
It depends on what 277 volt device you are trying to connect.
Can you connect a 3 wire 120 Volt with ground to a 2 wire House wire has black and white and ground Appliance has black red white and ground?
To answer this question fully the type of appliance has to be stated and its voltage.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no

How do you wire a electric garage heater drawing 5000 watts 240 volts to a30 amps circuit?
There should be two outputs on the 30 A breaker. You will need 10 AWG wire with 3-conductors and ground. Typically the wire colors will be Black, Red, White and (Green or bare). Connect black to one output of breaker and red to other output. Connect white to the white buss bar in main panel and green/bare to ground buss bar. At heater end connect the red and black to the 240 V leads, white to white and green/bare to the heater case.
How do you connect wire to a breaker?
There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
Where does the white wire connect on a six volt battery?
You don't say what you are connecting to the battery. If you have a black and white wire the best guess would be white to negative terminal and black to positive terminal. If you were connecting a 6V light bulb it really doesn't matter.

Connect the green wire to the brown striped black wire.
