The 7 Best Tools for Electricians in 2024
We recently asked electricians what they considered their top 5 essential tools—there were a few ties, so we’re sharing their top 7.
Electrical testing safety - Preparing for absence of voltage testing
Placing electrical equipment or systems in an electrically-safe work condition might seem simple, but there are several factors to consider.
Part 2: Electrical testing safety
If you find a circuit that shows voltage when there should be none, be careful what you do next. Creating an arc is unsafe and could get you fired or much worse. Be safe. Determine whether the voltage is induced by nearby, energized cables or if it is being backfed from an unknown source.
87V MAX数字万用表 vs 87V数字万用表
Compare IP rating, battery life and other features. What is the difference between the Fluke 87V MAX and the 87V digital multimeter?
What is true-RMS?
The need for true-RMS meters has grown as the possibility of non-sinusoidal waves in circuits has greatly increased in recent years. Some examples include variable speed motor drives, electronic ballasts, computers, HVAC, and solid-state environments.
What is Ohm’s Law?
Ohm’s Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
