RJ connectors are suitable for residential and office when used within the conditions of acceptability that would conform to NEC. And my furry friends chew all available Cat 5 stuff with no obvious effects, other than excessive salivation.
Did not want to bring this up, but here I go into the abyss. IMO, 1863 has some problems for your defined end-use because: - the probe in fig 8.1 does not conform to accessibility requirements in NEC for hazardous voltages - the scope disallows conformance with article 800 - definition of hazardous V and energy and VA does not conform to article 725 or UL1310. - the current protection tests are for a phone system/CO, but the scope disallows most telephone equipment - the standard does not address all user protection requirements as the standard is generally intended for professional equipment that is not accessible etc, etc, etc R/S, Brian > -----Original Message----- > From: Ilan Cohen [mailto:[email protected]] > Sent: Wednesday, May 26, 2010 9:57 PM > To: Brian O'Connell; [email protected] > Subject: RE: PoE which is not power limited. > > Hi Brian > > In your comments you say that you do not think RJ connecters are > suitable for Home usage.
