240 Volt Circuit With No Neutral
A double pole circuit breaker is clipped into both 120 buses at the same time so the voltage to the circuit is doubled.
240 volt circuit with no neutral. The transformer actually steps down the voltage to 240 volts so the two legs are a complete 240 volt circuit. These require both 120v and 240v so they do require a neutral. A 120 volt circuit has only one hot wire connected to the breaker plus a neutral wire connected to the neutral bus bar in the service panel.

This is why you. As noted in the posts above. The way you get a 240 volt circuit is simple. That looks quite in order.
In homes the most common 240v appliances are dryers and stoves. There is no current through the neutral for such loads. For 240 volt loads the current flows from one of the 120 volt lines to the other 120 volt line. True a straight 240v load does not need to have the neutral pigtail connected but many manufacures of hot tubs sometimes have 120 volt loads in their units much like a dryer that is fed with 240v but has 120 v loads such as light timers ect the breaker still senses the incoming power with the outgoing power for an inbalance.
On a pure 240v circuit no. Some need a neutral and some do not. A 3 wire 240 volt circuit has two hot wires each supplying 120 volts for a total of 240 and an equipment ground wire. That s why 240 volt circuits need two hot wires and a neutral to carry the electricity to the appliance plus a ground wire.
In north america there are a few different types of 240v loads. 3 a white wire called the neutral which completes the electrical circuit for the 120 volt accessories only. Load with or without neutrals may be connected to the load side of the gfi breaker. For the 240 volt circuits the loop is formed by l1 and l2 l1 l2.
All hut tubs i have wired do have a neutral for this reason but. For the 120 volt circuits in your house the neutral serves to complete the loop for current flowing from either l1 or l2 l1 neutral l2 neutral. Tapping 120volts off an existing 240volt branch circuit with a neutral is possible but is. Two pole gfi breakers require a line side neutral in order for the breaker electronics to work.
I hope this helps a little. 240v gfci work with no neutral. 1 a black wire which is often known as the hot wire which carries the current in to the fixture. There is no neutral.
For 120 volt circuits it flows through one of the 120 volt wires normally black and returns through the neutral wire normally white. 2 another hot wire which is red which also carries current in to the fixture. On a 240 120v circuit yes.
