ok all you grounding and bonding guys. if an installation conforms to 250,146 a or b does article 250.148 need to followed.
The conduit would be the EGC and it would be connected to the box. That complies with 250.148.That depends. 250.148 keeps you from daisey chaining the ground. But if you had metal conduit without an EGC it would be a moot point.
The use of self-grounding receptacles covers the rule in 250.146. You still have to connect the EGC wire to the box to comply with 250.148.but engineers are calling for an egc in emt most jobs now. why i dont know . and where i come from we only use self grounding outlets.
but engineers are calling for an egc in emt most jobs now. why i dont know . and where i come from we only use self grounding outlets.
and if i spliced the egc in a junction box to branch off to other outlets .what im getting is that in that junction box the egc will have to be bonded to the jb also
but engineers are calling for an egc in emt most jobs now.
That is correct.ok now would this also apply to feeders where an egc is pulled and a splice needs to be made
no tap off just a splice
so it would be only in a jb where i would branch out to a outlet .
ok so lets make it simple . the way we are all talking. if there is an egc pulled in any circuit conductors or even feeders .
if a splice is made the egc must be bonded to the JB and the outlet box . also in a feeder.
if this be the case. i wonder how many electrican really that. i can see the outlet box or a switch where a feeder would go to. but a jb splice box.
