Who Cares About 25 Ohms or Less?
Find out why the National Electrical Code "25 ohms or less" rule may have less to do with power quality than you think. Nearly all electricians and electrical inspectors are familiar with the National Electrical Code requirement in Sec. 25054, which requires the resistance to ground of a singlemade electrode (, ground rod) to be 25 ohms or less.

Gravel resistivity for grounding mat calculations ANSI ...
IEEE STD802000 has 10,000 Ohmm for wet gravel in Table7, while IEEE STD812007 has 1,000 Ohmm in Table 42. Is this a typo in Table7 Std802000 which gives un unsafe result by allowing a smaller grounding mat?
Two Tools for Testing Electrical Continuity The Spruce
These multipliers tell you that the reading on the ohm meter should be multiplied by the number indicated on the dial. For example, if your dial is set for X10 and the meter reads 50 ohms, the actual resistance number is 10 x 50, or 500 ohms. For simple continuity tests of switches and other devices, the multiplier settings are not important.
