Ilan,
For DC Powered units for use in Restricted Access Locations (RAL) in a CO environment, then a a field wiring compartment or box is not required. In such instances, either a terminal block for field wiring or 6 inch leads for field wiring is acceptable. You may chose to use a Listed field wiring junction box which is more expensive than providing simply a terminal block or 6 inch leads for field connections. One such manufacturer of junction boxes is Hoffman. Peter Ilan Cohen <[email protected]> wrote: Most of you guys are probably familiar with the field wiring requirements that ITE products must comply with. (mainly for DC powered units) When a unit does not comply and the terminal block is not suitable for field wiring than a manufacture has an option of using 6" leads (not a very favorable option but it is an option) or redesign of the power interface. A solution to this problem can be provided with an external box, which will be sold with the unit. The box clearly must comply with all the requirements of UL60950 (Terminal block suitable for filed wiring, electrical enclosure, access to Hazardous energies, etc.). Does any one know of connection boxes like that that are off the shelf and are UL approved for filed wiring? Any other ideas?
