Multi-plug adapters are well suited for distributing power to multiple low-energy electrical devices. The only multi-plug adapters permitted are the strip or block outlets that are equipped with a 15-amp circuit breaker. The approved adapters are to be used in conjunction with low-draw electrical items only (i.e. audio-visual equipment, computers, etc.).
