[RE-wrenches] myers hubs

[August Goers]

Hi Nick,

 

Don't you need to install a bonding bushing with an equipment jumper to bond
all conduits together regardless of whether you're using a Meyers hub or not
in a non-metallic enclosure? I might be misunderstanding you, but I don't
see how a bonding screw will do any good in a non-metallic enclosure.

yes you need a myers hub for the same above the bottom 1/3 and into the top
for your non-metalic enclousure. some will use a water tight connector
(raintight with a gasket ring). Either way you need a bonding bushing on
your connector or a myers hub with the bonding screw on the inside locknut
to bond together all the conduits coming into the enclosure.
i would suggest a hole saw definitely if you are working with fiberglass
combiner box and also for a pvc box because a unibit makes a cloud you dont
want around you in fiberglass and makes a beveled hole in a pvc box that can
make a seal difficult if your not careful.
