Can I use an extension cord permanently?

Using extension cords properly is critical to your safety. With continuous use over time, an extension cord can rapidly deteriorate, creating a potentially dangerous electric shock or fire hazard. Do not substitute extension cords for permanent wiring. Do not run through walls, doorways, ceilings, or floors.

How far can you run an extension cable?

We recommend that no extension lead be more than 15 metres long. Only use extension leads fitted with suitably insulated connectors and plugs. (Never join two lengths of flexible cable by twisting the bare ends of wires together.) Position an extension lead carefully to prevent any risk of damage.

Do extension cords lose power over distance?

A cord, based on its gauge, can power an appliance of certain wattage only at specific distances. As the cord gets longer, the current carrying capacity of the cordgets lower. For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance.

What is the longest extension lead?

The longest chain of extension cables is 22,860 m (75,000 ft), achieved by IES Residential, Inc (USA) in Dallas, Texas, USA, on 16 May 2018.

How long can a 12 gauge extension cord be?

A 12 gauge extension cord rated at 20 amps is a versatile extension for both indoor and outdoor use. Over 100-feet, it can safely handle 16 amps. It lets you run a single high-wattage power tool or two to three smaller tools or appliances.

Can extension cords be repaired OSHA?

Answer: Extension cords used in construction may be repaired, so long as the repair returns the cord to the “approved” state required by §1926.403(a). This section states, “All electrical conductors and equipment shall be approved.” Repairs of extension cords are therefore permitted under §1926.404(b)(1)(iii)(C).
