Electrical Question from Joe about 3-Phase 220 Volt Wiring Diagram
Electrical Question: Is the PE symbol the Earth Ground for an electrical power supply from another country?

I am getting ready to install a new power supply (pulse power).
The supply required is 220 volt, 3 phase, 60 cycles.
The landings are marked L1, L2, L3 and PE.
The question I have: Am I correct in thinking the PE landing is for the Earth Ground?
I’ve never seen this labeling. I should mention that this piece of equipment was spec out and imported from another country.

Thanks for your electrical question Joe.

Electrical Terminal Landing for the PE Wire Conductor

Application: Installing a 220Volt Circuit.
Skill Level: Intermediate to Advanced, Best installed by a Licensed Electrical Contractor. Work in electrical panels is not recommended for homeowners, non-experienced individuals or non-electricians.
Tools Required: Basic Electricians Pouch Hand Tools, electric drill, auger bits and extension cord.
Estimated Time: Depends on personal level experience, ability to work with tools and install 220 volt electrical circuit wiring.
Precaution: Identify the main circuit of the panel, turn it OFF and Tag it with a Note before working with the wiring or installing the 220 volt wiring and circuit breaker. Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock.
Notice: Installing an additional 220 volt circuit should be done according to local and national electrical codes with a permit and be inspected.

Wiring Connections to L1, L2, L3 and PE Terminal Blocks

The PE designates the termination for the Protective Earth or in our USA terminology the Ground.
This would be a Non-Current Connection.
NOTE: This connection is used for Fault Current only.

Electrical Tips to Help You Wire it Right
	The Safest Way to Test Electrical Devices and Identify Electric Wires! The Non-Contact Electrical Tester This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
	The Quickest Way to Check for Faulty Electrical Wiring! The Plug-In Outlet Tester This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring. It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
	Strip Off Wire Insulation without Nicking and Damaging the Electric Wire! The Wire Stripper and Wire Cutter My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.. The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
