SLIDE 1 (HOOK / COVER) ⚡ NEC Quick Hit: Switchboards, Switchgear & Panelboards (Part 1 - Article 408) ⚡
Switchboard scopes, 1000V voltage limits, and the strict ban on reconditioned panelboards—welcome to Article 408! How does the National Electrical Code regulate major electrical distribution equipment? Let's break down the fundamentals! 👇
SLIDE 2 (SCOPE & VOLTAGE LIMITS) What Article 408 Covers:
Equipment Scope: Covers switchboards, switchgear, and panelboards operating at voltages not over 1000 volts ac or 1500 volts dc, nominal.
Design & Location: Switchgear is completely enclosed and free-standing; switchboards are typically located in dedicated electrical rooms; panelboards contain switches and OCPDs for surface or flush mounting.
SLIDE 3 (RECONDITIONED EQUIPMENT RULES) What Can and Cannot Be Reconditioned:
Permitted Equipment: Reconditioned switchboards, switchgear, and individual sections of switchboards or switchgear are permitted, provided they are evaluated by the manufacturer or a qualified testing laboratory after damage.
Strict Prohibitions: Reconditioned panelboards are strictly not permitted to be installed under any circumstances.
SLIDE 4 (WRAP-UP) 💡 Apprentice Pro-Tip:
Never attempt to install a reconditioned panelboard during a service upgrade—while switchboard sections can be reconditioned and recertified, the NEC bans reconditioned panelboards entirely!
