These guides answer the questions facility teams bring to us most: what OSHA expects, which PPE category applies, what a compliant label must show, what an insurer means by an arc flash recommendation, and what the next NFPA 70E-2027 edition changes. Each guide opens with the direct answer and ends with what to do next.

Frequently asked questions
Question not here? Ask an engineer
Who writes these guides?
Our engineering team writes each guide from the published standards and federal regulations, and a US-licensed Professional Engineer reviews the technical content before it goes live. Where a rule depends on your state, your insurer or your equipment, the guide says so instead of guessing.
Can a guide replace an arc flash study?
No. A guide explains the rules; a study applies them to your actual equipment. Incident energy depends on your fault current, protective devices and working distances, so only a study of your system can give the values your labels and PPE choices must rely on.
How current are the guides?
Each guide cites the editions it relies on, such as NFPA 70E-2027 and IEEE 1584-2018. When a new edition is published, or a federal rule changes, we revise the affected guides and mark what moved, so you never have to wonder which version you are reading.
Can I ask a question that is not covered here?
Yes. Send it with the quote form or book a scope call, and an engineer answers it for your site. Questions that come up often become new guides, so the library grows from the problems facility teams actually raise with us.
Are the guides specific to my state?
They cover federal rules and national standards. State plans, local code amendments and state engineering rules can add to them. Our location pages cover state detail, and every study we deliver checks the rules that apply at your address before the work starts.
What should I read first?
Start with the OSHA guide if you are not sure a study is required, the label guide if an inspector or insurer flagged your labels, and the PPE guide if crews are unsure what to wear. Each one links to the next step for your situation.
