I don't see why not it will take up more space than regular building wire, so the capacity of the EMT will obviously be reduced

Can electrical wiring be on ground in crawlspace?
No, the electrical code requires that any wiring system be attached to an adjacent structure. A specific distance is required between holding points on the conduit or cable depending on the size of the conduit or cable. Home wiring is usually stapled every four feet.
What cable is needed to go from a generator to the electrical supply?
The cable that is used to connect from the generator is based on the size in kW's of the generator and the generator's breaker size rated in amps. It usually is a flexible cab-tire 4 wire cable if the generator is a portable type. If it is a stationary generator is has to be wired with a flexible conduit so as not to transmit vibration from the generator to the conduit system.
Some conduit fittings listed for use with cable wiring methods as well?
Some conduit fittings listed for use with cable wiring methods include connectors, couplings, elbows, and conduit bodies. These fittings are designed to provide a secure and reliable connection between the conduit and the cables, ensuring proper protection and organization of the wiring system.
What is the trade name for this cable romex?
NM (Non Metallic) Cable.
Do you have to ground a junction box if there is no splice?
No <<>> The NO answer above pertains to a metallic or PVC conduit system. In home wiring, with the type of wire being used it would be near impossible to drag a cable through a switch or receptacle junction box without cutting the cable. Once this cable is cut, the grounds have to be spliced together and this ground wire is then required by code to be grounded to the box.
What is the difference between armored cable and flexible metallic conduit?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
Where can you find a cable conduit?
An electrical conduit is a system for routing and protecting electrical wiring. A cable conduit can be found wherever electrical wiring is needed. This includes wiring in appliances or in the walls of a home.
Can you zip tie MI cable to conduit legally?
No, the electrical code requires that the mineral insulated cable be strapped at proper intervals and not be piggy backed on to other conduit structures.
Do electrical wire cables have to be clamped with cable connectors when they enter electrical panel box?
For cable not in conduit and intended to be installed without conduit, such as NM cable, yes. You must provide some form of connector that will hold the cable in place. A clamp is not the only kind of connector that will do this but is the most common.
What is Electrical sheathing?
Electrical Sheathing is various forms of metallic or non-metallic covering over conductors. Nonmetallic-Sheathed Cable is what is known by the brand name Romex.
Can electrical wiring be on ground in crawlspace?
No, the electrical code requires that any wiring system be attached to an adjacent structure. A specific distance is required between holding points on the conduit or cable depending on the size of the conduit or cable. Home wiring is usually stapled every four feet.
What is electrical NM cable?
type nm means non- metallic cover. it is the standard wiring used in housing nowadays.
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.
When installing surface mounted cable the best method of ensuring that it is kept straight is by?
When installing surface mounted cable the best method of ensuring that it is kept straight is by using more fasteners that is required by the electrical code. Another way is to install it into a conduit chase. The conduit can be fastened to the building using a level to keep it straight. The cable can then be pulled into the conduit.
What will be the effect if the threaded portion of conduit is not fully fitted to the coupling?
In the United States, the NEC requires that runs of conduit be continuous and connections be made wrench tight. If done properly this provides added grounding protection to your circuits. If a connection is left loose, that added grounding protection does not exist. There are times when threaded connections simply won't thread completely. This may require that the conduit threads be "run" with a threader to remove whatever is preventing this from happening. With experience you learn what is acceptable or not acceptable. Generally, if the connection is "wrench tight" and is otherwise secure, that is sufficient.
What is a cable tray?
A cable tray is a rigid structure to support electric cables.
