Assuming your local jurisdiction adopts the NEC as code, EMT must be fastened within 3 feet of each termination point (box, cabinet, conduit body, etc.) and every 10 feet of conduit run. Where the (horizontal run) EMT passes through a hole in a framing member is allowed to count as a support in lieu of a strap. You can place fasteners closer if you want, but not further apart.
There are two exceptions.
#1 You can increase distance "within 3 feet of a termination" to 5 feet where structural members do not readily permit fastening within 3 feet.
#2 For concealed work in finished buildings or prefinished wall panels where such securing is impractical, unbroken lengths (without couplings) of EMT shall be permitted to be fished.
Reference 2005 NFPA 70 (NEC) 358.30(A)(B)
Of course if you do not live in the US, or if your local municipality has adopted a different code or adopted the NEC with ammendments, your local law could be different. Check with the local building department to be sure.

What are the six methods of fix conduit?
The six methods of fixing conduit include: Conduit Hangers - These are brackets or clamps that attach the conduit to walls or ceilings. Straps - These are metal or plastic bands used to secure the conduit at specific intervals. Support Brackets - These provide additional support for heavier conduit runs, ensuring stability. Wall and Ceiling Clips - These are used to fasten the conduit directly to walls or ceilings. Junction Box Mounts - These attach conduit to junction boxes for secure connections. Conduit Fasteners - These include screws, anchors, or other hardware used to hold the conduit in place. These methods ensure that the conduit is securely installed and compliant with electrical codes.
What do you use to support conduit when is suspended in a ceiling?
To support conduit that is suspended in a ceiling, you typically use conduit hangers or straps. These devices secure the conduit to the structural elements of the ceiling, such as beams or joists, ensuring stability and compliance with electrical codes. Additionally, you may use threaded rods or wire for added support, especially over longer spans. Proper spacing between supports is also essential for maintaining the integrity of the installation.
How is an electrical conduit installed?
Conduit Installation: 9 Steps Step 1: Mark Conduit Placement: Using a measuring tape, mark the locations where the conduit will be installed, including entry and exit points, bends, junction boxes, and supports. Step 2: Cut and Prepare Conduit: Measure the required length for each conduit section based on your markings. Use a conduit cutter or hacksaw to make clean, straight cuts on the conduit. Step 3: Install Conduit Fittings: Attach the appropriate conduit fittings, such as elbows, couplings, or connectors, to the conduit sections. Step 4: Mount Conduit Supports: Install conduit straps or clamps at regular intervals along the conduit route. Step 5: Assemble the Conduit System: Connect the conduit sections and fittings together, ensuring a snug fit. Apply PVC conduit cement or glue to the inside of the fittings before joining them to ensure a watertight seal. Step 6: Pull Wires: Attach a fish tape or draw wire to the starting point of the conduit system. Carefully feed the fish tape through the conduit, pulling it along the desired path. Use lubrication, if necessary, to ease the wire pulling process. Step 7: Install Conduit Accessories: Install conduit bodies, junction boxes, or other accessories as needed for wire splices, changes in direction, or access points. Step 8: Verify and Secure Connections: Double-check all connections, ensuring they are properly aligned, secure, and free from any gaps or looseness. Step 9: Conduct Final Inspection: Inspect the entire conduit system to ensure it is properly aligned, securely mounted, and meets safety standards. Check for any visible defects, such as misalignments or damaged conduit. That's it.
Name three tools that you can use to protect a system against ESD as you work on it?
ANSI/ESD S20.20 covers the requirements of an ESD control program. The fundamental ESD control principles are: - Ground all conductors, including personnel - Insulators are high charging and cannot be grounded. Remove all non-essential insulators. Keep all process essential insulators at least 12" from ESDS or neutralize charges with ionizers - Outside an EPA, ESDS are to be packaged in closed ESD shielding bags or covered containers having shielding properties Grounding works great removing electrostatic charges. If opening a computer and handling circuit boards or electronics, the person should be grounded using a wrist strap connected to the ground of an AC electrical outlet or equipment ground. The ESD sensitive items should be placed on a grounded mat. A good tool to have is a Field Service Kit which includes a mat, a cord to ground the mat, and a wrist strap to ground the person. If attachment to the ground of an AC electrical outlet is not possible, one can use equipotential bonding. "When neither AC equipment [Equipment Grounding Conductor] or auxiliary grounds are available, an equipotential bonding system may need to be used. In this situation, all of the items in the system are bonded together so that the charge that resides on the elements will be shared equally and therefore there will be no potential difference between the items. Once this step has been completed it is safe to handle ESD sensitive parts without inducing damage. A real life example of this is often observed in office equipment field service operations. For safety reasons the service technician will often disconnect the AC power cord which detaches the equipment from ground. In order to safely install ESD sensitive products into the equipment, it is necessary to electrically connect or bond together the service technician, the equipment frame and the ESD sensitive product. Once bonded together an ESD event will NOT occur when the technician handles the product or installs it in the office equipment." [ESD Handbook ESD TR20.20-2008 section 5.1.3 Basic Grounding Requirements]
Why do people working on electronic equipment wear wrist straps that connect them to the equipment?
A: The reason is because as moving person you liable to generate kilo volts of static that when touching a circuit can and will destroy parts or worst unseen damage. The strap insure that no static can built because you are grounded to cause this kind of damage. In the industry it is mandatory if NASA has a project in the works. Get caught without it you are fired......
What are the best practices for installing outdoor cable conduit to protect and secure electrical wiring in an outdoor environment?
When installing outdoor cable conduit to protect electrical wiring, it is important to follow these best practices: bury the conduit at least 18 inches deep, use waterproof connectors, secure the conduit with straps or clamps, and regularly inspect and maintain the conduit to ensure it remains in good condition.
How can I safely and effectively run conduit through a wall for electrical wiring?
To safely and effectively run conduit through a wall for electrical wiring, follow these steps: Turn off the power to the area where you will be working. Plan the conduit route and mark the locations for holes in the wall. Use a stud finder to locate and avoid any studs or other obstacles in the wall. Drill holes for the conduit using a drill bit appropriate for the size of the conduit. Insert the conduit through the holes and secure it in place with conduit straps. Pull the electrical wires through the conduit, making sure to leave enough slack at each end. Connect the wires to the electrical outlets or switches as needed. Test the electrical connections and turn the power back on. Remember to follow all local building codes and regulations when running conduit for electrical wiring.

How can I install a conduit in a wall for running electrical wires safely and efficiently?
To install a conduit in a wall for running electrical wires safely and efficiently, follow these steps: Plan the conduit route and choose the appropriate size and type of conduit. Turn off the power to the area where you will be working. Cut a channel in the wall for the conduit using a saw or other appropriate tool. Insert the conduit into the channel and secure it in place with appropriate fasteners. Run the electrical wires through the conduit, making sure to leave enough slack for connections. Secure the wires in place within the conduit using appropriate clamps or straps. Seal any openings around the conduit to prevent drafts or moisture from entering. Test the electrical connections to ensure they are working properly before closing up the wall. Remember to always follow local building codes and regulations when installing electrical conduits.
