Can a 240 volt service have 208 volts on it?
No. A 3-wire 240 Volt service is a single phase service, and there should not be any 208 on such a system. BUT, if your premises is connected to a networked 3 phase wye connected service, you will have 120/208 Volts available, but not 240 Volts.
What is the difference between 208v and 240V single phase?
The difference between 208V three phase, and 240V single phase, is how the voltage is derived. 240V single phase is obtained by taking a single leg of three-phase power. 208V three phase is obtained by taking two legs of three-phase power. Will a 240v motor run on 208v?
Can a 208 volt high leg have a single breaker?
Here the B slots would never have just a single breaker in them but may have double or triple breakers for 240 volt only power (no neutral) or 3 phase power respectively. A 208 volt high leg (B leg) cannot power equipment rated for exactly 208 volts and also requiring a neutral.
What appliances need 240-volt service?
Some appliances in the home and some tools in a shop may require 240-volt service. This is still a single-phase service. 240-volt service is accomplished by using two 鈥渉ot鈥?120-volt lines. This doubles the available voltage to 240-volts. Most electric cookstoves, hot water heaters, and some other home appliances require this extra voltage.
