Do you need to use a Myers hub if you penetrate the bottom of a NEMA 3R junction box with rigid conduit?

Yes, if you are penetrating the bottom of a NEMA 3R junction box with rigid conduit, you should use a Myers hub to ensure a watertight seal and protect the wiring inside from environmental elements. Myers hubs are designed to provide a secure connection between the conduit and junction box.

Is it permitted to use flexible conduit over 6 feet in length as a grounding means?

No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use

To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?

If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.

When do you use a conduit bushing?

A conduit bushing is typically used to protect electrical wiring from damage as it passes through a metal enclosure or conduit fitting. It helps prevent the sharp edges of the conduit from damaging the insulation of the wires and provides a smooth surface for the wires to pass through, reducing the risk of abrasion or short circuits.
