The maximum allowable leakage current for any electrical device is 0.5 mA. This is equivalent to 0.5% of the rated current. This is a safety requirement to ensure that any current leakage is minimal and will not cause any harm to the user or damage to the device.Maximum allowable leakage current: 0.5 mAEquivalent to 0.5% of the rated currentIt is important to adhere to the safety requirements to ensure the safety of users and the protection of the device.
NEC recommends maximum allowable voltage drops not to exceed 3% on a branch circuit. For feeder/ branch combos the NEC recommends that the voltage shall not drop by more than 5% to the furthest outlet. The main consideration that is enforced is NEC 250-122. You must compensate your grounding conductor when you increase in conductor size to compensate for voltage drops. Direct bury or conduit: #4/0 copper provides for 2.95% #2/0 copper provides for 4.35% #1/0 copper provides for 5.19% Interestingly enough, using a separate calculator 3/0 copper with 3% voltage drop can be 780.5 feet long.

The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
The maximum percentage allowable is 65 percent. This can only be taken out if the garnishee does not support a second family and owes more than 12 weeks of back child support. If the garnishee does support a second family, the maximum is 55 percent if he owes more than 12 weeks of back child support, and 50 percent if he does not.

The maximum degrees of bending allowed for conduit typically ranges from 90 to 360 degrees, depending on the type and size of the conduit. It is important to consult local building codes and manufacturer specifications to determine the specific maximum degrees of bending allowed for a particular conduit. Incorrect bending can cause damage to the conduit and affect the performance of the electrical system.
