It is easier that you bend the conduit around the beam or pierce the conduit throough the beam, depending on how big the conduit is.

What are electrical conduit fittings used for?
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
What is metallic conduit?
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
What is the depth for electrical conduit?
3 feet.
What size conduit is needed for wiring in Indian houses?
The size of conduit is based on the size of the wires in it. The size of the wires depends on the load connected in the house. Without these other two values an answer can not be given.
What is the number of south African airways London branch in conduit street London?
2.5
When exist a junction box EMT conduit must be supported with how many inches?
When exist a junction box EMT, conduit must be supported within 18 inches.
When do you use a conduit bushing?
A conduit bushing is used when a conduit is terminated in a junction box or enclosure. Its purpose is to provide a smooth rounded surface so that when the wire is pulled into the conduit the insulation on the wire will not be damaged.
When is it required to bond a junction box?
If a junction box is part of an electrical conduit system then it is required to be bonded so as to make the whole electrical conduit system continuously conductive.
What are the advantages and disadvantages of steel junction boxs?
There are no advantages or disadvantages over which type of junction box to be used on electrical wiring. As long as the junction box is of an approved type (CSA or UL approved). It is cost or location which dictates which boxes will be used. PVC boxes for home wiring are the cheapest. Aluminium or steel are usually used in rigid or EMT conduit systems. PVC again when the conduit system involves underground wiring. In large electrical installations it is the electrical engineer that states what the conduit system type is and what type of electrical junction boxes that must be used.
How far from a junction box must emt conduit be strapped?
I always put the first EMT clip/strap 1 foot or 12 inches away from the junction box, then every 5 feet or so after that.
Is it necessary to ground at all metal junction boxes when using metal conduit or cable?
In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.
What is the main reason for connecting a ground wire to the end of a conduit being used to protect the wire?
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
What is the function of connectors?
The connectors are those things that exotic
How does pvc work?
Poly Vinyl Chloride composition is used for many products these days. Junction boxes, fittings and conduit are a few products that are made for the electrical trade that are made out of PVC. Most electrical engineered underground installations specify that PVC conduit be used because of its resistance to corrosion. Steel conduit systems, that PVC replaces, were found to disintegrate after a few years in the ground.
How many degrees of bend is allowed in a conduit run between j-boxs?
The electrical code states that there will be no more that four quarter bends between junction boxes. Keep in mind when conduit bending that an offset of two 45 degree bends is classed as a 90 degree bend. Offsets between two junction boxes uses up two of the four 90 degree bends allowed. If in a conduit run, the limit of 90 degree bends is utilized, always pull in stranded wire to make the pull go easier.
What is conduit wiring?
Conduit wiring is synonymous to wires in a pipe.
What is a taps?
A tap splice is a splice that is made usually in a mid span of aerial feeder conductors. It is used to connect a home from a utility company's secondary service drop on the street where the span is between poles and it is not convenient to connect a mid span home to either pole. Tap splices are also made in underground services where the utility feeders are in conduit between junction boxes. Each home along the route has an underground conduit from the junction box to the homes meter base. In the junction box where the home service wires connect to the utility feeders, this splice is known as a tap splice.
