If the two power supplies share a common ground, or can be made to, then it is no problem. However, the return wire must be sized for the sum of the 8 V and 12 V currents.
Is it possible both of the circuit is using the same ground GND connection?
3 Answers. You have to connect them, otherwise your circuit will most probably not work. If you do not connect both grounds, the voltage between these two grounds is somewhat random (determined by surrounding air, environment,…) and your signals might not be what you intended.
What is a common ground electrical?
Common ground, or simply common, isn’t a physical ground; rather, it’s just a reference point in a circuit for voltage measurements. That way, the circuit is said to have both positive and negative power supplies.
What if I have 2 ground wires?
The two ground wires must be wire-nutted together along with another 6-inch length of green or bare ground wire known as a pigtail. A grounded electrical outlet has three holes to provide a ground connection for three-prong plugged devices. Turn off the breaker controlling the outlet you’re working on.
What is the electrical symbol for ground?
Ground or Earth A ground symbol (IEC symbol 5017) identifies a ground terminal. It can be used for a zero potential reference point from where current is measured.
What happens when you ground an electrical outlet?
It doesn’t protect your electronic equipment from a power surge, though, because surge protectors work by shunting excess current through the ground wire to earth. To replace your two-prong outlet with a GFCI, start by turning off the breaker controlling the outlet circuit and unscrewing the outlet from the electrical box.
How do you connect a switch to a power source?
How to Connect Electrical Wiring for Switches and Outlets: The Most Common Method for Wiring Switches and Outlets from the Power Source. If playback doesn’t begin shortly, try restarting your device.
How to wire split outlets-the spruce?
How To Wire Split Outlets… When wiring split outlets, you’ll need to strip the wire sheath to access the wires. Using an NM (Romex) stripper or a razor knife, strip back about six inches of insulation from the wire. Cut off the excess insulation and separate the wires.
What does it mean when an electrical outlet is split?
A split outlet is a duplex electrical outlet that is split into two sections so that each section receives power from its own separate hot or powered wire. The outlet body itself is not physically split; it remains intact.
