Metal conduit must be buried to at least 6 inches.
Non-Metal conduit must be buried to at least 18 inches.
Direct bury wire must be buried to at least 24 inches.
This is what the NEC requires but your local codes may be even deeper. Check with your local utility to see what they require.

How many ground rods are needed for a 100 amp service?
If you're asking this, you shouldn't be installing an electrical service. --- This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself, or call a professional electrician. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.
How deep should a temporary electric service pole be set in the ground?
There is no specific depth stated. Two to three feed deep with staked angular support from the pole to the ground will do the job fine.
What is the proper grounding depth for a rod in wet land?
The wetness of the soil has no bearing on ground rods. Residential wiring requires two 8 foot long ground rods driven flush or just below the surface of the ground. One is mounted under the meter base and the other is mounted 6 feet to either side. <<>> The CEC (Canadian Electrical Code) requires two ten foot rods placed ten foot apart for the grounding system. The top of the rods are identified by diameter and length stamped into the rods. This is to prevent cutting the rods off if rock obstructions are encountered. If the rod will not pound into the ground any further it is bent 90 degrees and buried horizontally and again bent 90 degrees up to allow the top of the rod to protrude above the ground so as a connection can be made to it. In the new addition of the code it now allows a ground plate to be used as a grounding medium. Only one plate is required as it has more surface area than two ground rods. The plate is buried a one metre deep or a minimum of 600 mm if rock bottom is encountered.
What is the minimum depth in feet that a grounding rod must be driven into the ground?
Ground rods in the U.S. on a residential home are 8 foot long and are driven 8 feet into the ground. The top of both ground rods should be flush or just under the surface. One ground rod is placed directly under the meter base and another one is placed 6 feet to either side. They are connected together and grounded to the meter base with the correct size ground wire based on the amperage of the serviced being installed.
Clearance around an electrical panel?
The National Electric Code requires min. 3'0" there are several rules defined in section 110.26 of the NEC; for 600 volts or less it is: * left to right the minimum clearance is 30" or the width of the equipment, whichever is larger * in height, there should be 6' 6'' minimum height to stand in front of the equipment (exception for dwelling units for panels 200 amps or less) * the depth in front of the equipment varies depending on the voltage and surfaces of the opposite wall behind you: if the voltage is 150 volts to ground or less the depth of clearance is 30": as stated above; if the voltage is higher it depends of whether the opposite wall is insulated or not: if insulated the depth is 3' 6", if not insulated (such as cement block) the depth is 48"I refer to these rules as the "refrigerator rule": the clearance in front of the equipment in question requires a dedicated clear space roughly the size of a large refrigerator
What is the minimum trap seal depth requirement for a bath waste connection to a ground floor gulley?
50mm
What is the minimum trap seal depth requirement for a bath waste connected to a ground floor gulley?
600mm min
What should be considered when choosing the length of an anchor cable?
The depth of the water should be considered when choosing the length of an anchor cable. The anchor cable needs to be 4 to 7 times longer then the depth of the water.
What is the depth requirement for an under ground electric house wire?
The depth requirement for underground electric house wire varies depending on the type of wire and local building codes. As a general guideline, direct burial cables should be buried at least 18 inches deep in non-freezing soil. It is advisable to consult with a licensed electrician or your local building department for specific depth requirements in your area.
What is electrical depth sounding equipment called?
Sonar.
What is the depth requirement buried natural gas line?
The depth requirement for a buried natural gas line can vary depending on local building codes and regulations, but it is typically required to be buried at a minimum depth of 12 to 18 inches below the surface to protect it from damage. However, in some areas, the depth requirement may be deeper to meet specific safety standards. It is important to check with your local utility company or building department for the specific requirements in your area.
What is the analogy for if ascend is to height what is to descend?
Depth. To ascend is to go up, and to descend is go down. We measure the height of things above the ground and the depth of things below the ground.
A deep soil has to have a depth of how many inches?
A deep soil has to have a depth of 6 to 8 inches. Soils is what is on the ground.
What is the frost depth in Martinsville VA?
The frost depth refers to how deeply frost can penetrate into the ground. In Martinsville, Virginia, the frost depth is around 18 inches deep.
How deep do you bury 120v wire?
Minimum coverage for non vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 600 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 450 mm. Minimum coverage for vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 900 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 600 mm.
Should armoured cable be buried a certain depth?
Yes, armored cable should typically be buried at a minimum depth of 24 inches to protect it from damage and meet electrical code requirements. However, check local building codes for specific depth requirements in your area.
How does the depth of the snow cover influence the depth to which the ground freezes?
A thicker snow cover acts as an insulating layer, trapping heat and limiting the depth to which the ground freezes. The snow prevents the ground from losing heat to the cold air above, resulting in shallower freezing depths. Conversely, a thinner snow cover allows more heat to escape, leading to deeper ground freezing.
