Surge protectors are usually rated in joules, which are a way to measure energy, and in essence, the more joules the better. For computer systems, 1,000 joules or more is recommended. This joule rating gives you a sense of how long the device can protect against surges and spikes.
Most commercial motor vehicles in Wisconsin require a USDOT Number and it must be provided at the time of registration. If you are required to have a USDOT Number, and cannot produce the number for verification, your vehicle registration application will not be processed until a valid number is provided.
The FMCSA monitors and ensures compliance with motor carrier safety (all carriers) and commercial (for-hire, non-exempt carriers) regulations. Companies may find they are subject to registration requirements for both safety (safety registration) and commercial regulation (operating authority registration). Companies subject to the safety requirements are also required to obtain a USDOT Number. The FMCSA registration process requires that companies define the type of Motor Carrier, Broker, Intermodal Equipment Provider (IEP), Cargo Tank Facility, Shipper and/or Freight Forwarder business operation they plan to establish.
