I am looking for a good resource for IP65 rated motors with CE Mark.
I require 2 motors.
One will be 1/3 HP 230Vac 50Hz and will operate a circulator pump.
The second will be 1/2HP 180Vdc 50 Hz and will operate a product pump.
Both will be continuous duty and serve in laboratory batch...

You will have to provide more specifics.
1 What type of installation?
2 What type of power involved?
3 What voltages involved?

5 Total number and size of conductors in wireway?
There are instances where such an installation would pass NEC given a few...
Thanx guys....
good info...
received response from manufacturer via vendor today stating that their UL approved clearance for these elements 6KW @ 575V is a minimum of 1/4" phase to phase......

With quality projects, or any projects...
Peebee and myself are in agreement. While I emphasized on a grounding path hardwire system, he emphasized on the electronic component version.
Good info.
Response at this date may not be helpful, but here goes.
This is a somewhat open-ended question.

Transient Voltage Surge Suppression, in its basic form, is NOT fused.
For said protection in given system, esp high-rise or medical installation, same is accomplished by separate grounding conductor from bonding point(s) in the system (preferrably at the main, but acceptable at points through...
Point well taken....UL has served as an agency of third party review....
CE Mark is a Self Declaration issuance.
On the matter of color harmonization, thank you for your input.
