Not usually. The primary current for neon tube Transformers are not that high and can be added to existing circuits. Many of these types of neon transformers just plug into a normal wall receptacle. If it is a large neon sign it is a good idea to use a dedicated circuit for isolation purposed when servicing the sign.

Does a microwave always need a dedicated circuit?
No
Does a freezer absolutely need a dedicated outlet?
Current code say that a freezer or any appliance needs to be on it's own circuit. It will still work if it is not on a dedicated circuit.
Do air conditioners need there own circuit breaker?
Yes. Due to their higher current requirements it is recommended that air conditioners be connected to their own dedicated circuit and thus have their own circuit breaker.
Does a fire alarm control panel need a dedicated branch circuit?
Under the NFPA Fire Alarm Code, the control panel must have its own dedicated circuit, the circuit must be labeled "Fire Alarm Circuit" and the handle of the circuit breaker must be colored red. Other rules apply in jurisdictions that adopt other standards, or for other types of fire alarms. For example, under New Hampshire Fire Code, you are PROHIBITED from installing self-contained smoke alarms on a dedicated circuit.
Do you need a dedicated circuit for an electric stove?
Always. Check the spec for amps and use an online calculator to figure for wire size.
Does a microwave need a 15 or 20 amp circuit?
By code you're supposed to have a dedicated 20 amp circuit. But if you have an existing 15 amp circuit it might be fine for now if your microwave is 1400 watts or less and there's nothing else drawing power from that circuit. But if your running it new definitely run a 20 amp circuit dedicated on 12 gauge wire. That will allow you to use any microwave you want now and in the future.
Can a dedicated circuit share a neutral?
It depends on:what you are calling a dedicated circuitWhether there is ANY possibility that the neutral could be required to carry a load in excess of the rating of the wire.First we have to make certain that we're talking the same language, second we have to consider the fire hazard involved. (although, if we're looking at safety, we would need to reverse the two)The simple answer is No.The term "dedicated circuit" is not defined in the code. But in practice the term refers to a circuit that is run for a particular purpose, often to one piece of equipment or receptacle (outlet). Sharing a neutral contradicts the principle of a dedicated circuit.Sharing a neutral would expose the circuit to electrical elements such as harmonics. A dedicated circuit is intended to avoid such problems.
Does the microwave need a curcuit?
Yes, every Microwave should have it's own dedicated circuit as some consume 15-18 amps.
Does an LCD TV need a dedicated electrical outlet?
A dedicated circuit assures that you do not have any external interference on the TV. The quality of today's TV's are very sensitive to fluctuations in the signal. Any interference will be reflected in the picture quality. If the circuit is not dedicated, a regular circuit will be shared sometime in the future to a wall plug outlet that a device will be plugged in. You have no idea what "noise" will be generated and reflected on the TV. Why take that chance. Fluorescent lights are incredibly noisy and will show on the TV.
Can an espresso machine with a 20A 240V Leviton plug be powered without rewiring?
You need a dedicated circuit for that. You cannot power a 220V device off 110V.
In voice communications circuit switching is preffered over packet switching Give reasons?
You need a dedicated circuit for carrying voice communications that cannot be shared with others. That won't happen with packet switching, which will result in choppy and non-understandable conversations.
What might make the air conditioner and the dryer go out at the same time this happened twice in the same month?
It must be on the same circuit in your breaker box. They both need dedicated circuits for them.
