Reposted from response at alternate listing for this subject: No. The exception deal with the disconnecting portion of overcurrent protection. In other words, if you have the ground fault protection, you are 1) required to have it present at all the locations listed, and 2) now allowed to...

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...

No. The exception deal with the disconnecting portion of overcurrent protection. In other words, if you have the ground fault protection, you are 1) required to have it present at all the locations listed, and 2) now allowed to have the ground fault protection automatically disconnect in...

You will have to provide more specifics. 1 What type of installation? 2 What type of power involved? 3 What voltages involved? 4 Size of wireway? 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...... Thanx for your time.

equipment manufactured in US.....end user in Canada.... basically is a NEMA requirement......... UL standards also apply...

I have received some heating elements that have been constructed out of the norm for this vendor. The concern at this point is that proper clearances have not been maintained phase to phase. 575V 3Ph Anyone have any information or a source that will outline these clearances....NEMA website...

Relax... You are not required to install GFCI protection on your commercial dishwasher...or residential for that matter. The utilization of GFCI is primarily for personnel protection. This is why you will see GFCI's is areas where water may be present....countertops in baths, kitchens...

Sadly enough, the scenario you have laid out is not uncommon. While the Owner and his representatives establish a projected budget for the project, realistic or not, with the current economic times, they are able to shop bids much easier than previously. 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. The first obvious response is that it depends on the particular standard -- in other words....maybe not... British Standards that are currently in place, are obviously valid for British...

EN 60204-1

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...

Pardon, but wanted to thank you ccaserta, for yours is the type of feedback that makes this a worthwhile forum...

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. Upon specific inquiry, UL stated to us that such was not the case. It has not been a problem with any client thus...

Thank you for your input ccaserta, and you are correct in the application of EN 60204-1. Additionally, having conferred with UL, who is certified for third party inspections for CE Mark, the only wire color actually harmonized at this point is the green/yellow protective conductor. However, in...

Thanks guys.... Tracked down Global Engineering and couple other sources...found what I wanted.. One site actually gave me the option to download in PDF...no shipping....cheaper.... Had to dig a couple levels deep. but found exactly what I needed.

THHN is only readily available down to 14awg.....16awg and lower are manufactured as TFFN....for most manufacturers is actually the same insualtion and elastomeric cover, being that most wires are valued as more than one category. Also, you will see the insulation value rise to 105C

This has been a matter on whic I have watched local inspectors flip-fllop, of course all the while denying ever having thought the opposite. The current thought among them for the last 10 years has been that if 3 phase conductors share the same neutral, regardless of single or multiple loads...

Not sure exactly of your term "cross basement". However, no EMT is required in residential basement or attic applications unless 3 stories above grade is exceeded. In said instance, EMT would be one option.
